In the Westminster Standards. We argue that baptism is a sign and seal. I know what my answer would be and what I have learned reading Puritans and certain Reformers. However I have heard varying answers as to just what is meant by a "seal" by others in the paedobaptist camp. As I am a Presbyterian, this has made conversations with Credo-only baptists very difficult. So what do we mean exactly when we say that Baptism is a seal? What is the best way to counter those who would say that Baptism is not a seal?
