Not much time but I want to offer a few points (few related to the subject at hand specifically).

[quote:yu1kny8v]Four criteria were used for determining the books of the New Testament.[/quote:yu1kny8v]
Does your friend adhere to Sola Scriptura? Because the argument presented disproves it in favor of the Church. None of these four criteria is the Bible or is in the Bible; they were the product of the Church.

Why does your friend reference Jewish sources for the canon of Scripture when the Christian Church, the pillar and foundation of truth, already existed? This same Church used the Deuterocanonical books and officially affirmed their inspiration in the 4th century.
