Heaven in Christianity in the context of "Virgin Mary"

The Keys of Heaven, also called Saint Peter's keys, refers to the metaphorical keys of the office of Saint Peter, the keys of the Gates of Heaven, or the keys of the kingdom of Heaven. It is explicitly referenced in the Bible in Matthew 16:19.

The Session of Christ or heavenly session is a Christian doctrine stating that Jesus is seated at the right hand of God the Father in Heaven—the word "session" is an archaic noun meaning "sitting". Although the word formerly meant "the act of sitting down", its meaning is somewhat broader in current English usage, and is used to refer to a sitting for various reasons, such as a teaching session, or a court or council being in session. The New Testament also depicts Jesus as standing and walking in Heaven, but the Session of Christ has special theological significance because of its connection to the role of Christ as King. The Session of Christ is one of the doctrines specifically mentioned in the Apostles' Creed, where "sitteth on the right hand of God the Father Almighty" immediately follows the statement of the Ascension.

Queen of Heaven (Latin: Regina Caeli) is a title given by the Catholic Church and Eastern Orthodoxy, to Mary, mother of Jesus, and, to a lesser extent, in Evangelical Lutheranism and Anglicanism. The title has long been a tradition, included in prayers and devotional literature and seen in Western art in the subject of the Coronation of the Virgin from the High Middle Ages, long before the Church gave it a formal definition status.

The Catholic teaching on this subject is expressed in the papal encyclical Ad Caeli Reginam, issued by Pope Pius XII in 1954. Therein, the pope states that Mary is called Queen of Heaven because her son, Jesus Christ, was charged as being "King of Israel" and the heavenly king of the universe. This would render the mother of the king as the "queen mother" of Israel.

The Divine Comedy (Italian: Divina Commedia, pronounced [diˈviːna komˈmɛːdja]) is an Italian narrative poem by Dante Alighieri, begun c. 1308 and completed around 1321, shortly before the author's death. It is widely considered the pre-eminent work in Italian literature and one of the greatest works of Western literature. The poem's imaginative vision of the afterlife is representative of the medieval worldview as it existed in the Western Church by the 14th century. It helped establish the Tuscan language, in which it is written, as the standardized Italian language. It is divided into three parts: Inferno, Purgatorio, and Paradiso.

The poem explores the condition of the soul following death and portrays a vision of divine justice, in which individuals receive appropriate punishment or reward based on their actions. It describes Dante's travels through Hell, Purgatory, and Heaven. Allegorically, the poem represents the soul's journey towards God, beginning with the recognition and rejection of sin (Inferno), followed by the penitent Christian life (Purgatorio), which is then followed by the soul's ascent to God (Paradiso). Dante draws on medieval Catholic theology and philosophy, especially Thomistic philosophy derived from the Summa Theologica of Thomas Aquinas.

In Christianity, sanctification (or in its verb form, sanctify) literally means "to set apart for special use or purpose", that is, to make holy or sacred (compare Latin: sanctus). Therefore, sanctification refers to the state or process of being set apart, i.e. "made holy", as a vessel, full of the Holy Spirit. The term can be used to refer to objects which are set apart for special purposes, but the most common use within Christian theology is in reference to the change brought about by God in a believer, begun at the point of salvation and continuing throughout the life of the believer. When used in this sense, sanctification is known as growth in grace. Many forms of Christianity believe that this process will only be completed in Heaven, but some (particularly conservative Quaker and Methodist traditions, inclusive of the Holiness movement) believe that entire sanctification is possible in this life.

Purgatory (Latin: purgatorium, borrowed into English via Anglo-Norman and Old French) is a belief in Catholic theology. It is a passing intermediate state after physical death for purifying or purging a soul before entering Heaven. A common analogy is dross being removed from gold in a furnace.

In Catholic doctrine, purgatory refers to the final cleansing of those who died in the State of Grace, and leaves in them only "the holiness necessary to enter the joy of heaven"; it is entirely different from the punishment of the damned and is not related to the forgiveness of sins for salvation. A forgiven person can be freed from his "unhealthy attachment to creatures" by fervent charity in this world, and otherwise by the non-vindictive "temporal (i.e. non-eternal) punishment" of purgatory.

Christian eschatology is a branch of study within Christian theology which deals with the doctrine of the "last things", especially the Second Coming of Christ, or Parousia. The word eschatology derives from two Greek roots meaning "last" (ἔσχατος) and "study" (-λογία) – involves the study of "end things", whether of the end of an individual life, of the end of the age, of the end of the world, or of the nature of the Kingdom of God. Broadly speaking, Christian eschatology focuses on the ultimate destiny of individual souls and of the entire created order, based primarily upon biblical texts within the Old and New Testaments.Christian eschatology looks to study and discuss matters such as death and the afterlife, Heaven and Hell, the Second Coming of Jesus, the resurrection of the dead, the rapture, the tribulation, millennialism, the end of the world, the Last Judgment, and the New Heaven and New Earth in the world to come.

Eschatological passages appear in multiple places in the Bible, in both the Old and New Testaments. A number of extra-biblical examples of eschatological prophecies also exist, as well as extra-biblical ecclesiastical traditions relating to the subject.
