Why Bible Believing Christians Need the Catholic Church. Scripture is a gift from God....but only through the Catholic Church can you experience the fullness of the Christian Faith. In argumnets both lucid and thorough Benedictine Abbott Basil Christopher Butler shows why the Bible can never be he sole criterion of faith nor serve as a sufficient foundation for the full Christain life to which Jesus calls us. Although the books of the Bible are inspired by God, they are insufficient as the full measure of faith. There is only one source, shows Butler, where Christains can turn for the full truth.
