The religious historian Augustus Neander wrote of the first-century Christians: “The practice of infant baptism was unknown at this period. . . . That not till so late a period as (at least certainly not earlier than) Irenaeus [c. 140-203 C.E.], a trace of infant baptism appears, and that it first became recognised as an apostolic tradition in the course of the third century, is evidence rather against than for the admission of its apostolic origin.”—History of the Planting and Training of the Christian Church by the Apostles, 1864, p. 162.
