Catholicism does not deny the deity of Jesus Christ. Nor does it put an adulterous war mongering pedophile on a par with Jesus Christ... well, I am not familiar with all the popes, was there one or two that would fit that description? Islam is anti-Christ. Muslims revere and idealize Mohammed, is the point. To Muslims, Mohammed supersedes Jesus Christ. Which is a bit odd, because their book acknowledges that Jesus had a miraculous birth (virginal) and Mohammed admits that he (Mohammed) performed no miracles while Jesus did. Their book also acknowledges that Jesus will be coming back even though they deny His crucifixion and subsequently His resurrection as well.
I do think Catholicism is Satanic. Here is why.
They pray to Mary and Saints. The rosary is a popular one.
They believe that salvation comes from works. (7 Sacraments)
They revere the pope, priests and all of their clergy.
Even the lower clergy like the bishops and priests have to follow what the pope says. They believe the pope can do no wrong. That's not right. Only Christ is perfect.
Have you read any of the stories they have of different virgins and saints? OMG they are really creepy.
They believe in things that are not in our Bible, like purgatory.
Also, when a person dies, the family can have mass each anniversary of their death to pray for their loved one (you know so that they can get out of purgatory faster!

). The thing is that each of these masses costs a lot of money. Why do you think the Catholic church is so well off?
They're deceitful, they believe in salvation by works, not by faith. They don't really have a relationship with Christ.
I was Catholic for 14 years and when I changed to Christianity, I was awe struck with just the idea of knowing Christ and Him knowing me. I had never even heard that before!
What does God want most of all? A relationship with his sons and daughters. The Catholic church doesn't really teach that. They believe that only the priests have direct communication with God. This is why they can only repent to priests and not go directly to God.
I think that if a religion is taking away what God wants most (a relationship with us), then is must be controlled by the enemy.
Sorry, I didn't mean to rant. I was just giving my opinion on Catholicism.
And I don't hate Muslims or Catholics. My best friend is a Muslim and half of my family is Catholic. I love them, but I know they could be doing so much better if they weren't involved with these terrible religions.
