In this sermon, titled "The Baptism of Infants," Charles Coffin argues that because infants have a sinful nature through the instrumentality of their fallen parents and because God desires infants to be saved, a visible or manifest interest in the covenant entitles infants not less than adults to a regular membership [in the visible church] properly sealed [i.e. by baptism]. Coffin further asserts that if an infant's parents are church members, the child is a member as well because in all public covenant transaction with men God has uniformly included children in their parents, as branches in their stock or root; and admitted them to the same covenant seals and privileges as far as their capacity would allow.
