Calgar,
Most of the New Testament was preserved by oral Tradition long before it was written. Keep in mind the Apostles/Disciples “preached” the Gospel.
Here are a few passages to consider. There are many more that point to Tradition.
Corinthians 11:
1 Be imitators of me, as I am of Christ. 2 Now I commend you because you remember me in everything and
maintain the traditions even as I delivered them to you.
2 Thessalonians 2:
14 To this he called you through our gospel, so that you may obtain the glory of our Lord Jesus Christ. 15 So then, brothers, stand firm and hold to the** traditions** that you were taught by us, either by our
spoken word or by our
letter.
John 20:
30 Now Jesus did many other signs in the presence of the disciples, which are not written in this book. . .
Luke 1:
1 Inasmuch as many have undertaken to
compile a narrative of the things that have been accomplished among us, 2 just as those who from the beginning were eyewitnesses and ministers of the word have delivered them to us, 3 it seemed good to me also, having followed all things closely for some time past, to write an orderly account for you, most excellent Theophilus, 4
that you may have certainty concerning the things you have been taught.
John 21:
25 Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written.
Acts 8:
26 Now an angel of the Lord said to
Philip, “Rise and go toward the south to the road that goes down from Jerusalem to Gaza.” This is a desert place. 27 And he rose and went. And there was an
Ethiopian, a eunuch, a court official of Candace, queen of the Ethiopians, who was in charge of all her treasure.
He had come to Jerusalem to worship 28 and was returning, seated in his chariot, and he was reading the prophet Isaiah. 29 And the Spirit said to Philip, “Go over and join this chariot.” 30 So
Philip ran to him and heard him reading Isaiah the prophet and asked, “Do you understand what you are reading?” 31 And he said, “How can I, unless someone guides me?” And he invited Philip to come up and sit with him. 32 Now the passage of the Scripture that he was reading was this:
“Like a sheep he was led to the slaughter
and like a lamb before its shearer is silent,
so he opens not his mouth.
33 In his humiliation justice was denied him.
Who can describe his generation?
For his life is taken away from the earth.”
34 And the eunuch said to Philip, “About whom, I ask you, does the prophet say this, about himself or about someone else?” 35 Then Philip opened his mouth, and beginning with this Scripture he told him the good news about Jesus. 36 And as they were going along the road they came to some water, and the eunuch said, “See, here is water! What prevents me from being baptized?” 38 And he commanded the chariot to stop, and they both went down into the water, Philip and the eunuch, and he baptized him. 39 And when they came up out of the water, the Spirit of the Lord carried Philip away, and the eunuch saw him no more, and went on his way rejoicing. 40 But Philip found himself at Azotus, and as he passed through he preached the gospel to all the towns until he came to Caesarea.
Philippians 4:
9 What you have
learned and received and heard and seen in me—practice these things, and the God of peace will be with you.
Tradition is inescapable. We all yield to it one way or the other. There is an abundance of modern tradition. Is there a TV Evangelist who doesn’t have a book out?
Peace to you, my friend,
Anna
If I hear something long enough, I might actually believe it and buy the bike (and by bike, I mean Catholicism.)
