What isn't man made? If men didn't pass down or god give the bible how would we ever have known about Jesus, Moses etc.
How would we know about our history had man not written it down?
Everything on this earth now is pretty much man made, science, isms, processed foods, governments, laws, books, stand up comedies etc. So if we go by everything man made is fkd up then what's left really? The bible is the one thing not man made but the word of God. The Catholic Church you say is man made do you? That was the first church which saint peter by the blessing of God and has kept christs teachings all along.
A man made version of Christianity is the Protestant denomination if anything, Martin Luther refused to accept the catholic doctrine which was straight from Jesus and started his own clan (Protestantism).
Man made things have led to many great things only look at the health sector and what surgeons can do now with man made instruments. Just because there is a fingerprint of man doesn't automatically mean it's evil. What it does mean though is that evil can still be a choice for a man and then it becomes evil.
Just like a Catholic priest. There could be one god fearing doing all what the doctrine of Christ has told then the other man will be like no I will give in to my evil human urges.
Where is pedophilea allowed in the church from the bible and doctrine? How does it represent the church? The priest represents the church not the act.
P.s you should have kept going with your scripture studies. Why'd you let a human get in the way of the word of god?
