What is this lie from hell sacred tradition of the Bible?

I hadn't heard of the "Sacred Tradition", but then I don't listen to a lot of crap. I have had a problem with the idols in the church myself. I felt it very difficult when my husband was ill and his sister would bring friends and they would say the rosary for him. He was dying with cancer and grasping at straws. His family was so upset with me because he was not buried from a traditional Catholic ceremony. I informed them if they were so worried about his salvation they should have done something while he was alive. He'd been attending a Methodist church with me, and it was how it was. If they thought carrying his body down the aisle of a church was going to save his immortal soul they better think again....well you can well imagine my relationship with them now... there is none, except with his younger sister who is not Catholic either. Guess that says alot....they were real christian about the whole ordeal....not!
