Other than a confession, and a desire to be Baptized, what constitutes a "credible profession?" What was the Apostles' practice?
Ummm "Believe on the Lord Jesus Christ and be baptized"?
Are you sure it wasn't "Believe on the Lord Jesus Christ, be examined for 7 years, and then be baptized?" That's what happened at Pentecost, right?
Come on, guys. Jesus suffered the little children to come to him, and said that our faith should be like theirs. Small children may not be ready for the meat, but I have no idea where some people are getting that a five-year-old can't understand simple propositions. The bible never talks about an "intellectual difficulty" of the message. It is merely sin that causes us not to want what God has.
What does a paedo do with an adult convert who wants to be baptized? Do they question the convert first to see if he understands the faith or is the only requirement that they claim to be a Christian?
