In Evangelism we normally preach to Catholics about using extra biblical things such as there Catacatism but how many traditions do we have that may not go against scripture directly but we still practise.
Matthew 15:1-9
1 Then came to Jesus scribes and Pharisees, which were of Jerusalem, saying, 2 Why do thy disciples transgress the tradition of the elders? for they wash not their hands when they eat bread. 3 But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition? 4 For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death. 5 But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; 6 And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition. 7 Ye hypocrites, well did Esaias prophesy of you, saying, 8 This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me. 9 But in vain they do worship me, teaching for doctrines the commandments of men.
Do our traditions go against and make the commandment of god to non effect!
