“The clarity of infant baptism is not to be founded upon any clear statements in the Scriptures, but upon the belief that there is unity between the old and new covenant. Hence, to succeed in this proving infant baptism, we must dig deeper and examine the continuity and discontinuity in between old and new covenants, as well as the relationship between the Old Testament Israel and the New Testament church. Showing the differences between circumcision and baptism is not enough; the differences between the old and new covenants must be established as well.
“This is critical to understand. One cannot consistently except covenant theology as expressed by paedobaptist without also accepting the teaching that the old and new covenants are essentially the same covenant. To put it bluntly, One cannot except this form of covenant theology without believing that the covenant that was established on Mount Sinai was part of the covenant of grace.”

The covenants are the main issue to grapple when wrestling with anything surrounding their logical implications.
