Galatians 1:8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
Now, if scripture is not the only source for what the apostles taught please show another source where the apostles taught the assumption of Mary.
Perhaps you missed the part where it says "we have preached unto you," not "contained in Scripture." It is the church that preaches. No where in the Bible does it state that it is the only source of truth.
No, I didn't miss that part. "That part" is my point. Paul said if someone taught something they didn't they were to be considered accursed. It would therefore be incumbent on Catholics to show some proof that the apostles taught the assumption of Mary or they are to be considered accursed. If Catholics think that scripture is not the only source they need to provide another source for the apostles teaching the assumption of Mary. If you cannot do that I will consider those that teach the assumption of Mary to be accursed by God.
The Mormons have Joseph Smith and his anointed followers for prophecy and truth, the JW's have Ellen White and Roman Catholics have their prophets the popes.. Actually the apostles taught from the scriptures, as did Christ.. the scriptures contain the complete revelation of God...
THE TESTIMONY OF THE NEW TESTAMENT TO THE INSPIRATION OF THE OLD TESTAMENT. Jesus has been proven to be not only a credible witness, but a messenger from God. In all His teachings He referred to the divine authority of the Old Testament (Mt. 5:17-18; 8:17; 12:40-42; Lk. 4:18-21; 10:25-28; 15:29-31; 17:32; 24:25-45; Jn. 5:39-47). He quoted the Old Testament 78 times, the Pentateuch alone 26 times. He quoted from Genesis, Exodus, Leviticus, Deuteronomy, Psalms, Proverbs, Isaiah, Jeremiah, Ezekiel, Daniel, Hosea, Amos, Jonah, Micah, and Malachi. He referred to the Old Testament as “The Scriptures,” “the word of God,” and “the wisdom of God.” The apostles quoted 209 times from the Old Testament and considered it “the oracles of God.” The Old Testament in hundreds of places predicted the events of the New Testament; and as the New Testament is the fulfillment of, and testifies to the genuineness and authenticity of the Old Testament, both Testaments must be considered together as the Word of God.
The New Testament reveals the Old
The new Testament IS the teaching they were being given orally then written ...
