Why are the writings of the Fathers accepted as conclusive on certain matters which the New Testament leaves indeterminate?

Because the Christian world receives the books of the New Testament on the testimony of the early Fathers of the Church, who certify that these books had been transmitted to their times by the Churches which had originally received them; thus, in settling the question of the genuineness of the books of the New Testament, all Christendom regards this testimony as conclusive. The same Fathers who testify as to the matter of fact regarding the New Testament also testify as to the matter of fact regarding the Baptism of infants. If their testimony is accepted as authoritative and conclusive on so important a matter as the genuineness of the Bible, it must certainly be accepted as authoritative and conclusive in other matters pertaining to their time.
