I believe every word Jesus said, when he was speaking to synagogue attending Jews...
I believe everything Jesus said to the Jews before the 'church' was instituted...
I believe everything Jesus said to the Jews who were still under the Laws and Ordinances of Israel...
I believe everything Jesus said to those who were under the law and faith who had not yet been given the new revelation in Romans 3...
Rom 3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
You don't have Romans 3:21 in your catechism, do you....
Good for you. So you reject all the New Testament books after the Gospels, eh?
