2 Thes 2:15 Therefore, bretheren, stand fast, and hold the traditions which you have been taught, whether by word, or our epistle.
2 Thes 3:6 Now we command you, bretheren, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he recieved from us.
The problem that we have with scripture alone is that it (scripture) doesn’t say what these traditions are. It gives some insight into what the early Church was doing (baptism -Acts 22:16, meeting on Sunday -Acts 20:7, sharing the body and blood of our Lord -Acts 20:7, 1 Cor 11:23-29) But, it is the Church and only the church that has faithfully preserved these things. And not just these three, but others. Scripture says, " And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written." -Jn 21:25. I guess scripture says not everything is in scripture.
So, what other things? Were any of them important? Did Jesus tell the Apostles to write everything down, like He told John in Rev 1:11? NO! Does anyone think that Paul realized he was writing holy scripture when he asked Timothy to send his cloak to him? (2 Tim 4:13) NO! It has always been assumed, (for 1500 years, anyway) that we needed both scripture and the Church, which, according to scripture is “the pillar and ground of truth” (1 Tim 3:15)
The article also claimes that the early church fathers never say that the Church was passing down any traditions. This is very wrong, as anyone who bothers to actually open a book from one of the fathers could plainly see. But, here’s one quote I found easily:
“The teaching of the Church has indeed been handed down through an order of succession from the Apostles, and remains in the churches even to the present time. That alone is to be believed as truth which is in no way at variance with ecclesiastical and apostolic tradition.” -Origen (c. AD 230)* Fundamental Doctrines, preface 2*
I only read about 1/4 of the way through the article, but… REALLY!
