Trinitarianism in the context of "God the Father"

Eastern Orthodox theology is the theology particular to the Eastern Orthodox Church. It is characterized by monotheistic Trinitarianism, belief in the Incarnation of the divine Logos or only-begotten Son of God, cataphatic theology with apophatic theology, a hermeneutic defined by a sacred Tradition, a catholic ecclesiology, a theology of the person, and a principally recapitulative and therapeutic soteriology.

Heresy is any belief or theory that is strongly at variance with established beliefs or customs, particularly the accepted beliefs or religious law of a religious organization. A heretic is a proponent of heresy.

Heresy in Judaism, Christianity, and Islam has at times been met with censure ranging from excommunication to the death penalty.

Various early Christian writers wrote gospels and other books, some of which were canonized as the New Testament canon developed. The Apostolic Fathers were prominent writers who are traditionally understood to have met and learned from Jesus's personal disciples. The Church Fathers are later writers with no direct connection to the disciples (other than the claim to apostolic succession). Early Christian apologists tried to defend Christianity against its critics, especially the Ancient Greek and Roman philosophers. Dates given, if not otherwise specified, are of their writings or bishopric, not of their lives.

The Maryland Toleration Act, also known as the Act Concerning Religion, was the first law in North America requiring religious tolerance for Christians. It was passed on April 21, 1649, by the assembly of the Colony of Maryland, in St. Mary's City in St. Mary's County, Maryland. It created one of the pioneer statutes passed by the legislative body of an organized colonial government to guarantee any degree of religious liberty. Specifically, the bill, now usually referred to as the Toleration Act, granted freedom of conscience to all Christians. (The colony which became Rhode Island passed a series of laws, the first in 1636, which prohibited religious persecution including against non-Trinitarians; Rhode Island was also the first government to separate church and state.) Historians argue that it helped inspire later legal protections for freedom of religion in the United States. The Calvert family, who founded Maryland partly as a refuge for English Catholics, sought enactment of the law to protect Catholic settlers and those of other religions that did not conform to the dominant Anglicanism of Britain and her colonies.

The Act allowed freedom of worship for all Trinitarian Christians in Maryland, but sentenced to death anyone who denied the divinity of Jesus. It was revoked in 1654 by William Claiborne, a Virginian who had been appointed as a commissioner by Oliver Cromwell; he was an Anglican, a Puritan sympathizer, and strongly hostile to the Catholic Religion. When the Calverts regained control of Maryland, the Act was reinstated, before being repealed permanently in 1692 following the events of the Glorious Revolution, and the Protestant Revolution in Maryland. As the first law on religious tolerance in British North America, it influenced related laws in other colonies and portions of it were echoed in the writing of the First Amendment to the United States Constitution, which enshrined religious freedom in American law.
