Yeah, you got a point regarding doing something to understand the word of God. But the Church has already done this thing for almost 2000 years, there is no reason for me to duplicate their work. And if given that the Catholic Church is wrong, what Christian church do you think I will join next? Remember, there are thousands of them. I don't think my lifetime would be enough to scrutinized each of them just know which church has the real truth. Besides none of the other Christian churches claims authority over the Bible, so that settles the issue for me.
To put it properly, it is the Church which is higher than the Bible. The Bible was created for the Church and not the Church was created for the Bible. Jesus Christ built a church and not a Bible.
Jesus Christ is the head of the whole Church, so it is only logical that the Church is higher than the Bible.
Yes, I myself has read something about it in the Bible. But that too is subject to interpretation because it is not presented in black and white by the Bible.
Anyway, try to read this link. This article presents a highly intellectual discussion regarding veneration of saints and images.

No problem.
