Answer: The sacraments of Baptism and the Lord's Supper differ, in that Baptism is to be administered but once, with water, to be a sign and seal of our regeneration and ingrafting into Christ, and that even to infants; whereas the Lord's Supper is to be administered often, in the elements of bread and wine, to represent and exhibit Christ as spiritual nourishment to the soul, and to confirm our continuance and growth in him, and that only to such as are of years and ability to examine themselves.
