Indeed, the Westminster Larger Catechism 166 requires that “infants descending from parents either both or but one of them professing faith in Christ…are…to be baptized. Genesis 17:7f; Galatians 3:9f; Colossians 2:11f; Acts 2:38f; Romans 4:11f; First Corinthians 7:14; Matthew 28:19; Luke 18:15f; Romans 11:16.”
Rightly does the Westminster Confession 28:4f therefore conclude that “also the infants of one or both believing parents are to be baptized…. It be a great sin to contemn or neglect this ordinance! Luke 7:30 & Exodus 4:24-26.”
