We must recognize the fact that for thousands of years a lot of people were uneducated and could not read.
For that reason the denominational institutional church leaders came up with creeds , rituals , beads , confessionals, golden candle sticks , and whatever props helped the believer "act out his faith".
We can poo-poo some of these things today but we should accept that at one time that was how it was done and the church has survived.
We are quick to point out doctrinal errors , or non scriptural teachings, but we do our own versions of them today.
Just try to disagree with someone's doctrine here today , and they will jump all over you faster than the pope and his Cardinals.
Some things never change , only the disguises and scenery change.
Today Christians still continue to jump all over one another and then mix in the word love to justify their actions.
In the old days there were a hundred large denominations with various doctrinal differences. Now there are millions of small ones .... US
