>Celibacy
That's the Catholic Church. What does the Bible say about celibacy?
>(1 Corinthians 9:5) We have authority to lead about a sister as a wife, even as the rest of the apostles and the Lord’s brothers and Cephas, do we not?
>(1 Timothy 3:2) The overseer should therefore be irreprehensible, a husband of one wife, moderate in habits, sound in mind, orderly, hospitable, qualified to teach,
>(1 Timothy 3:12) Let ministerial servants be husbands of one wife, presiding in a fine manner over children and their own households.
>(Titus 1:6) if there is any man free from accusation, a husband of one wife, having believing children that were not under a charge of debauchery nor unruly.
>(Colossians 2:23) Those very things are, indeed, possessed of an appearance of wisdom in a self-imposed form of worship and [mock] humility, a severe treatment of the body; but they are of no value in combating the satisfying of the flesh.
>>Idolization of Mary/Saints
You're not supposed to do that. That is using icons as mediators to God. God already arranged a mediator for you.
>(Hebrews 12:24) and Jesus the mediator of a new covenant, and the blood of sprinkling, which speaks in a better way than Abel’s [blood].
>(1 Timothy 2:5) For there is one God, and one mediator between God and men, a man, Christ Jesus,
>(Hebrews 9:15) So that is why he is a mediator of a new covenant, in order that, because a death has occurred for [their] release by ransom from the transgressions under the former covenant, the ones who have been called might receive the promise of the everlasting inheritance.
>(Hebrews 8:6) But now [Jesus] has obtained a more excellent public service, so that he is also the mediator of a correspondingly better covenant, which has been legally established upon better promises.
You can't pray to Mary because that is still bypassing the true mediator which is Jesus.
>Pope
There is no Pope in the Bible. All the Apostles are equal.
