, one of the Twelve Disciples, became an apostate. The Christian understanding of apostasy is "a willful falling away from, or rebellion against, Christian 'truth.' Apostasy is the rejection of Christ by one who has been a Christian ...", but the
Reformed Churches teach that, in contrast to the
conditional salvation of
Lutheran,
Roman Catholic,
Methodist,
Eastern Orthodox, and
Oriental Orthodox theology, salvation cannot be lost once accepted (
perseverance of the saints). "Apostasy is the antonym of conversion; it is deconversion."
B. J. Oropeza states that apostasy is a "phenomenon that occurs when a religious follower or group of followers turn away from or otherwise repudiate the central beliefs and practices they once embraced in a respective religious community." The
Ancient Greek noun ἀποστασία
apostasia ("rebellion, abandonment, state of apostasy, defection") is found only twice in the New Testament (Acts 21:21; 2 Thessalonians 2:3). However, "the concept of apostasy is found throughout Scripture."
The Dictionary of Biblical Imagery states that "There are at least four distinct images in Scripture of the concept of apostasy. All connote an intentional defection from the faith." These images are: Rebellion; Turning Away; Falling Away; Adultery. • Rebellion: "In classical literature apostasia was used to denote a coup or defection. By extension the Septuagint always uses it to portray a rebellion against God (Joshua 22:22; 2 Chronicles 29:19)." • Adultery: One of the most common images for apostasy in the Old Testament is adultery. The debate has centered on the issue of apostasy and salvation. Based on the concept of God's sovereign grace, some hold that, though true believers may stray, they never totally fall away. Others affirm that any who fall away were never really saved. Though they may have "believed" for a while, they never experienced regeneration. Still others argue that the biblical warnings against apostasy are real and that believers maintain the freedom, at least potentially, to reject God's salvation. In the recent past, in the
Roman Catholic Church the word was also applied to the renunciation of
monastic vows (
apostasis a monachatu), and to the abandonment of the
clerical profession for the life of the world (
apostasis a clericatu) without necessarily amounting to a rejection of Christianity.
Penalties Apostasy was one of the sins for which the early church imposed perpetual penance and excommunication. Christianity rejected the removal of heretics and apostates by force, leaving the final punishment to God. As a result, the first millennium saw only one single official execution of a heretic, the
Priscillian case. Classical
canon law viewed apostasy as distinct from heresy and schism. Apostasy
a fide, defined as total repudiation of the Christian faith, was considered as different from a theological standpoint and from heresy, but subject to the same penalty of death by fire by
decretist jurists. The influential 13th-century theologian
Hostiensis recognized three types of apostasy. The first was conversion to another faith, which was considered traitorous and could bring confiscation of property or even the death penalty. The second and third, which was punishable by expulsion from home and imprisonment, consisted of breaking major commandments and breaking the vows of religious orders, respectively. A
decretal by
Boniface VIII (pope between 1294-1303) classified apostates together with heretics with respect to the penalties incurred. Although it mentioned only apostate Jews explicitly, it was applied to all apostates, and the
Spanish Inquisition used it to persecute both the
Marrano Jews, who had been converted to Christianity by force, and to the
Moriscos who had professed to convert to Christianity from Islam under pressure. Temporal penalties for Christian apostates have fallen into disuse in the modern era. They apply the term to a range of conduct, including open dissent with the denomination's doctrines, celebration of "false religious holidays" (including Christmas and Easter), and participation in activities and worship of other religions. A member of the denomination who is accused of apostasy is typically required to appear before a committee of elders that decides whether the individual is to be shunned by all congregants including immediate family members not living in the same home. Baptized individuals who leave the organization because they disagree with the denomination's teachings are also regarded as apostates and are shunned.
Watch Tower Society literature describes apostates as "mentally diseased" individuals who can "infect others with their disloyal teachings". Former members who are defined as apostates are said to have become part of the
antichrist and are regarded as more reprehensible than non-Witnesses.
Latter-day Saints (Mormonism) Members of
the Church of Jesus Christ of Latter-day Saints (LDS Church) are considered by church leadership to engage in apostasy when they publicly teach or espouse opinions and doctrines contrary to the teachings of the church, or act in clear and deliberate public opposition to the LDS Church, its doctrines and policies, or its leaders. This includes advocating for or practicing doctrines like those followed in apostate sects, such as plural marriage, more commonly known as
polygamy. In such circumstances the church will frequently subject the non-conforming member to a
church membership council which may result in membership restrictions (a temporary loss of church participation privileges) or membership withdrawal (a loss of church membership). == Hinduism ==
