Құдайдың үш бірлігі туралы формула

In Christianity, phrase referring to the Trinity

The Trinitarian formula is the phrase "in the name of the Father, and of the Son, and of the Holy Spirit" (; in nomine Patris et Filii et Spiritus Sancti), or words to that form and effect, referring to the three persons of the Christian Trinity. It is often followed by an "amen". The Trinitarian formula is used in baptism as well as in numerous prayers, rites, liturgies, and sacraments. One of its most common uses apart from baptism is when Roman Catholics, Eastern and Oriental Orthodox, Lutherans, Anglicans, Methodists, and others make the sign of the cross while reciting the formula.

According to the doctrines of Roman Catholicism, Oriental Orthodoxy, Eastern Orthodoxy, and most forms of Protestantism, such as Lutheranism, Calvinism and Anglicanism, a baptism is not valid unless the Trinitarian formula is used in the administration of that sacrament. Consequently, they may not recognize religious communities that baptize without this formula – e. g., Unitarians, Branhamists, Frankists, Jehovah's Witnesses, and Oneness Pentecostals, all of whom deny the Trinity – as Christian religions. This is also the case with baptisms within The Church of Jesus Christ of Latter day Saints (LDS church). Although LDS members baptize with the same Trinitarian formula, they reject the Nicene Trinitarian conception and regard the three persons of the Trinity as being distinct personages united not in substance, but in dominion and purpose. Baptism according to the Trinitiarian formula is seen as being a basis for Christian ecumenism, the concept of working towards the eventual unity of Christians belonging to different Christian denominations.
