“Only the Orthodox and Catholic Churches can trace their origin to Apostolic times.”
Tradition is not truth or integrity. It is tradition. The RCC has shown itself throughout history to be bereft of both, regardless of its much heralded, self-proclaimed tradition.
Might be a good idea to remember that.
I went to Biblegateway and I did a search on "tradition." Below are some passages that I found.
1 Corinthians 11:2
Now I commend you because you remember me in everything and maintain the traditions even as I delivered them to you.
2 Thessalonians 2:15
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.
2 Thessalonians 3:6
Now we command you, brothers, in the name of our Lord Jesus Christ, that you keep away from any brother who is walking in idleness and not in accord with the tradition that you received from us.
So clearly, the traditions handed on by the apostles, whether oral or written, are essential and valid. Catholics call these traditions, Apostolic Tradition.
On the other hand, erroneous human traditions are condemned in Scripture.
Colossians 2:8
See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
Mark 7:8
You leave the commandment of God and hold to the tradition of men.”
