1. A bishop must be the husband of one wife. Catholic priests are unmarried.
2. A bishop must have children. Catholic priests do not have children.
Relevant verses:
3. The Bible says false religions forbid people to marry. The Catholic church forbids the marriage of priests:1 Timothy 3:2 KJV A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;
1 Timothy 3:4 KJV One that ruleth well his own house, having his children in subjection with all gravity;
(This verse also reinforces that salvation is by faith alone.)1 Timothy 4:3 KJV Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
And doesn't the Catholic church also demand that people spend some days as vegetarians or at least eating only fish?
4. Catholic church has priests wearing long robes, which Christ explicitly stated that people should beware of such people:
5. Christ explicitly explained that we should not call other men Father (according to faith, not heritage), because only God the Father is our Father according to the faith.Luke 20:46 KJV Beware of the scribes, which desire to walk in long robes, and love greetings in the markets, and the highest seats in the synagogues, and the chief rooms at feasts;
6. Catholicism says that Mary is the mediator between God and Man. The Bible says that Christ is the Mediator:Matthew 23:9 KJV And call no man your father upon the earth: for one is your Father, which is in heaven.
7. Christ explicitly tells us NOT to pray in vain repetitions, but Catholicism has multiple prayers that are chanted in repetition:1 Timothy 2:5 KJV For there is one God, and one mediator between God and men, the man Christ Jesus;
8. Don't let any false prophet deceive you out of your inheritance of eternal lifeMatthew 6:7 KJV But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking.
9. Catholicism has statues and graven images which the Ten Commandments forbid, because it is a form of idol worship.Colossians 2:18 KJV Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,
10. Salvation for Christians is simply by believing in Christ and His Works. Salvation for Catholics is supposedly faith in Christ, plus works, which include sacraments such as: baptism, matrimony, communion, church attendance, etc. If a person doesn't have good enough works, they will perish. However, in Christianity, Christ kept all the commandments for us and overcame the law, then He died for our sins. Therefore Christ has done all the work, and all we must do to be saved as true Christians is to trust in Him. Works come thereafter to do what is pleasing in the sight of God.Exodus 20:4 KJV Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth.
I could expand this list, to include things such as monks (just like another false religion: Buddhism), nuns, praying to Mary instead of to God, rosary beads, purgatory, etc. But rest assured, Catholicism is not Christianity. It is a false version that has simply dominated the world and deceived everyone into thinking that it is Christianity when it is just a diversion.
Anyone can be saved though. All they have to do is believe, Catholic or not. But Catholicism itself is pure idolatry.
