Based on Islam religion, Jesus is just one of the prophet send by God and in Islamic version the name we call is Eesa more sounds similar right.
So this could be the reason why both religions have similarities.
Christians and Islam believe in Abraham too, that's another similarity.
while in roman catholicism the devil is some kind of punisher and judge.
There is a misconception about Catholicism and Christianity, these two are different too.
Scriptures and verses of the bible describes about the devil.
John 8:44
Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
Thief = evil
John 10:10
The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.
There is another religion that I've known lately which is called
Bahai. It was said that you can be a Christian, Muslim, Buddhist, a Jew and any other religion you have at the same time as long as you'll follow their teaching. It's new to me.
