Answer:
I would say they both transmit a certain knowledge of God. However, where Scripture(the Bible) is settled and absolute in truth and has true authority, tradition is pliable; it changes, and has opinions, and is formed and maintained by people, who don't really have any authority or hold any absolute truth of themselves.
If a person does something that the Bible tells them they should do, that is good and right in the eyes of Truth. When people begin to form opinions about what seems right, but not clearly mandated by the Word of God, it is a tradition of men, and not of God. There are so many examples of traditions that are very plainly not 'scriptural', but they are still done anyway, and for several thousand years at that! The Jewish Talmud is an example. Though there are many 'good' things a person may learn from it, it isn't Scripture. Jesus dealt with it when the Pharisee's chastised his disciples for not washing hands before eating. He basically derided them for teaching the traditions of men like they were the Word of God.
Now, we know through science and reason that it is a good thing to wash our hands before we eat because of germs and such, that it is good for us. The point is, don't tell me that I am not doing the will of God if I don't wash my hands! The pitiful thing is, people do that to other people, and they are wrong. And I think most 'religious' people act that way out of ignorance to Truth. It is a sad thing to say that most people have never read the whole Bible, so they take another person's word that the Bible teaches this or that.
Examples: (And mind you, I realize most of the people in these groups are nice people and are trying to please God with the knowledge that they have!)
Mormons- they hold that the book of Mormon has as much authority as the Bible(which it doesn't- it is a book of ideas from a person with no authority(and unfortunately has deceived millions))
Muslims- the whole thing is make believe- no Jesus, no Heaven (again, pitiful-hundreds of millions deceived)
Catholics- their traditions have destroyed nations and millions of good people for 1700 years. If the Bible says you get saved by asking Jesus to forgive your sins, thereby receiving God's grace through your faith in the sacrifice that Jesus made for you- and the Catholics say, no: you get saved by joining our church and getting baptized, and asking Mary for forgiveness- which one is right? They both say to do something different than the other. Things different are not the same. And that is a small example of the error you will find in this tradition-ridden 'church'.
This stuff is important; eternity is real, God is real, the Bible is true(KJV 1611).
So, if you would like to follow God in Spirit and in Truth, I have found that the Independent Baptist Churches are the ones to go to. But they aren't all right; some do things that I don't believe follow the Word. Make sure a church uses the King James Bible Old Version 1611, and the preacher is dedicated to serving God and winning souls and teaching the people Bible truth and not opinions!
I personally have no gain in this recommendation; I am just a Christian that wants to please God and help people get to Him...I am tired of seeing people living in pain and trouble and sorrow, and dying without any real hope of Heaven according to Truth.
