The practice of infant sprinkling was instituted by the Roman Catholic Church, as admitted by their own historians, and did not receive general acceptance until about the 12th century.
A Roman Catholic priest, Brenner, has made the following statement with regard to this matter – “For thirteen hundred years was baptism generally and regularly an immersion of the person under the water, and only in extraordinary cases a sprinkling or pouring of water; the latter was moreover, disputed as a mode of baptism, may even forbidden” (Historical Exhibition of Administration of Baptism. Page 306.)
A quotation from Cardinal Gibbons, (1834-1921) another Roman Catholic authority, is also most illuminating. Cardinal Gibbons, an American, was the author of several books on Roman Catholicism. He stated, “For several centuries after the establishment of Christianity, baptism was usually conferred by immersion; but since the 12th Century the practice by sprinkling has prevailed in the Catholic Church, as the manner is attended with less inconvenience than baptism by immersion.”
