When John Henry Newman entitled his spiritual autobiography Apologia Pro Vita Sua in 1864, he was playing upon both this connotation, and the more commonly understood meaning of an expression of contrition or regret. Christian apologists employ a variety of philosophical and formal approaches, including ontological, cosmological, and teleological arguments. The Christian presuppositionalist approach to apologetics utilizes the transcendental argument for the existence of God. Tertullian was a notable early Christian apologist. He was born, lived and died in Carthage. He is sometimes known as the "Father of the Latin Church". He introduced the term Trinity () to the Christian vocabulary and also probably the formula "three Persons, one Substance" as the Latin "tres Personae, una Substantia" (itself from the Koine Greek "treis Hypostaseis, Homoousios"), and also the terms Vetus Testamentum (Old Testament) and Novum Testamentum (New Testament).

Hinduism Hindu apologetics began developing during the British colonial period. A number of Indian intellectuals had become critical of the British tendency to devalue the Hindu religious tradition.
