Revelation in the context of Freethought

Philosophy (from Ancient Greek philosophía lit. 'love of wisdom') is a systematic study of general and fundamental questions concerning topics like existence, knowledge, mind, reason, language, and value. It is a rational and critical inquiry that reflects on its methods and assumptions.

Historically, many of the individual sciences, such as physics and psychology, formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the history of philosophy include Western, Arabic–Persian, Indian, and Chinese philosophy. Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation. Indian philosophy combines the spiritual problem of how to reach enlightenment with the exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues about right social conduct, government, and self-cultivation.

Theology is the study of religious belief from a religious perspective, with a focus on the nature of divinity and the history behind religion. It is taught as an academic discipline, typically in universities and seminaries. It occupies itself with the unique content of analyzing the supernatural, but also deals with religious epistemology, asks and seeks to answer the question of revelation. Revelation pertains to the acceptance of God, gods, or deities, as not only transcendent or above the natural world, but also willing and able to interact with the natural world and to reveal themselves to humankind.

Theologians use various forms of analysis and argument (experiential, philosophical, ethnographic, historical, and others) to help understand, explain, test, critique, defend or promote any myriad of religious topics. As in philosophy of ethics and case law, arguments often assume the existence of previously resolved questions, and develop by making analogies from them to draw new inferences in new situations.

The magisterium of the Catholic Church is the church's authority or office to give authentic interpretation of the word of God, "whether in its written form or in the form of Tradition". According to the 1992 Catechism of the Catholic Church, the task of interpretation is vested uniquely in the Pope and the bishops, though the concept has a complex history of development. Scripture and Tradition "make up a single sacred deposit of the Word of God, which is entrusted to the Church", and the magisterium is not independent of this, since "all that it proposes for belief as being divinely revealed is derived from this single deposit of faith."

An angel is a spiritual heavenly, or supernatural entity, usually humanoid with bird-like wings, often depicted as a messenger or intermediary between God (the transcendent) and humanity (the profane) in various traditions like the Abrahamic religions. Other roles include protectors and guides for humans, such as guardian angels and servants of God. In Western belief-systems the term is often used to distinguish benevolent from malevolent intermediary beings.

Emphasizing the distance between God and mankind, revelation-based belief-systems require angels to bridge the gap between the earthly and the transcendent realm. Angels play a lesser role in monistic belief-systems, since the gap is non-existent. However, angelic beings might be conceived as aid to achieve a proper relationship with the divine.

Prophets in Islam (Arabic: ٱلْأَنْبِيَاء فِي ٱلْإِسْلَام, romanized: al-anbiyāʾ fī al-islām) are individuals in Islam who are believed to spread God's message on Earth and serve as models of ideal human behaviour. Some prophets are categorized as messengers (Arabic: رُسُل, romanized: rusul; sing. رَسُول, rasool), those who transmit divine revelation, most of them through the interaction of an angel. Muslims believe that many prophets existed, including many not mentioned in the Quran. The Quran states: "And for every community there is a messenger." Belief in the Islamic prophets is one of the six articles of the Islamic faith.

Muslims believe that the first prophet was also the first human being Adam, created by God. Many of the revelations delivered by the 48 prophets in Judaism and many prophets of Christianity are mentioned as such in the Quran with the Arabic versions of their names; for example, the Jewish Elisha is called Alyasa', Job is Ayyub, Jesus is 'Isa, etc. The Torah given to Moses (Musa) is called Tawrat, the Psalms given to David (Dawud) is the Zabur, the Gospel given to Jesus is Injil.

In Islam, Muhammad (Arabic: مُحَمَّد) is venerated as the Seal of the Prophets who transmitted the eternal word of God (Qur'ān) from the angel Gabriel (Jibrīl) to humans and jinn. Muslims believe that the Quran, the central religious text of Islam, was revealed to Muhammad by God, and that Muhammad was sent to guide people to Islam, which is believed not to be a separate religion, but the unaltered original faith of mankind (fiṭrah), and believed to have been shared by previous prophets including Adam, Abraham, Moses, and Jesus. The religious, social, and political tenets that Muhammad established with the Quran became the foundation of Islam and the Muslim world.

According to Muslim tradition, Muhammad was sent to the Arabic community to deliver them from their immorality. Receiving his first revelation at age 40 in a cave called Hira in Mecca, he started to preach the oneness of God in order to stamp out idolatry of pre-Islamic Arabia. This led to opposition by the Meccans, with Abu Lahab and Abu Jahl as the most famous enemies of Muhammad in Islamic tradition. This led to persecution of Muhammad and his Muslim followers who fled to Medina, an event known as the Hijrah, until Muhammad returned to fight the idolaters of Mecca, culminating in the semi-legendary Battle of Badr, conceived in Islamic tradition not only to be a battle between the Muslims and pre-Islamic polytheists, but also between the angels on Muhammad's side against the jinn and false deities siding with the Meccans. After victory, Muhammad is believed to have cleansed Arabia from polytheism and advised his followers to renounce idolatry for the sake of the unity of God.

Ethics involves systematizing, defending, and recommending concepts of right and wrong behavior. A central aspect of ethics is "the good life", the life worth living or life that is simply satisfying, which is held by many philosophers to be more important than traditional moral conduct.

Most religions have an ethical component, often derived from purported supernatural revelation or guidance. Some assert that religion is necessary to live ethically. Simon Blackburn states that there are those who "would say that we can only flourish under the umbrella of a strong social order, cemented by common adherence to a particular religious tradition".

In religion, a false prophet or pseudoprophet is a person who falsely claims the gift of prophecy or divine inspiration, or to speak for God, or who makes such claims for evil ends. Often, someone who is considered a "true prophet" by some people is simultaneously considered a "false prophet" by others, even within the same religion as the "prophet" in question. In a wider sense, it is anyone who, without having it, claims a special connection to the deity and sets themself up as a source of spirituality, as an authority, preacher, or teacher. Analogously, the term is sometimes applied outside religion to describe someone who fervently promotes a theory that the speaker thinks is false.

Theism is broadly defined as the belief in the existence of at least one deity. In common parlance, or when contrasted with deism, the term often describes the philosophical conception of God that is found in classical theism—or the conception found in monotheism—or gods found in polytheistic religions—or a belief in God or gods without the rejection of revelation, as is characteristic of deism.

Non-theism and atheism is commonly understood as non-acceptance or outright rejection of theism in the broadest sense of the term (i.e., non-acceptance or rejection of belief in God or gods). Related (but separate) is the claim that the existence of any deity is unknown or unknowable; a stance known as agnosticism. Agnostic theism is a personal belief in one or more deities along with acceptance that the existence or non-existence of the deity or deities is fundamentally unknowable.

Deism (/ˈdiːɪzəm/ DEE-iz-əm  or /ˈdeɪ.ɪzəm/ DAY-iz-əm; derived from the Latin term deus, meaning "god") is the philosophical position and rationalistic theology that generally rejects revelation as a source of divine knowledge and asserts that empirical reason and observation of the natural world are exclusively logical, reliable, and sufficient to determine the existence of a Supreme Being as the creator of the universe. More simply stated, Deism is the belief in the existence of God—often, but not necessarily, an impersonal and incomprehensible God who does not intervene in the universe after creating it, solely based on rational thought without any reliance on revealed religions or religious authority. Deism emphasizes the concept of natural theology—that is, God's existence is revealed through nature.

Since the 17th century and during the Age of Enlightenment, especially in 18th-century England, France, and North America, various Western philosophers and theologians formulated a critical rejection of the several religious texts belonging to the many organized religions, and began to appeal only to truths that they felt could be established by reason as the exclusive source of divine knowledge. Such philosophers and theologians were called "Deists", and the philosophical/theological position they advocated is called "Deism".

Christian philosophy includes philosophies carried out by Christians or in relation to the religion of Christianity. Christian philosophy emerged with the aim of reconciling science and faith, starting from natural rational explanations with the help of Christian revelation. Several thinkers such as Origen and Augustine of Hippo believed that there was a harmonious relationship between science and faith, others such as Tertullian claimed that there was contradiction; others tried to differentiate them.

There are scholars who question the existence of a Christian philosophy itself. These claim that there is no originality in Christian thought, and its concepts and ideas are inherited from Greek philosophy. Thus, Christian philosophy would protect philosophical thought, which would already be definitively elaborated by Greek philosophy. However, Catholic scholars Philotheus Boehner and Étienne Gilson claim that Christian philosophy is not a simple repetition of ancient philosophy, although they owe to Greek science the knowledge developed by Plato, Aristotle and the Neoplatonists. They even claim that in Christian philosophy, Greek culture survives in organic form.
