Roman Catholic AnswerFirst of all, Catholics and Christians are the same thing. Second, of course Catholics believe in Judgment Day. from The Catechism of the Catholic Church, second edition, English translation 1994681 On Judgment Day at the end of the world, Christ will come in glory to achieve the definitive triumph of good over evil which, like the wheat and the tares, have grown up together in the course of history.
I do believe that god has a set special day for judgment but I don't think that anyone knows that day.
Muslims believe many of the same things about angels as Christians do, but there is a greater focus on Gabriel over Michael, since Gabriel facilitated the revelation of the Qur'an. In terms of Judgment Day, the general idea of Judgment Day and the Apocalypse are the same in Islam. Of course, the fundamental difference is that when God sits in judgment, the "correct" answer to what religion you belong to is Islam, not Christianity and Muhammad sits with God as He judges instead of Jesus.
A minority of Christians who believe in preaching hate, and believe that manipulating the bibles teaching for their own purposes, claim that we will burn in hell forever. I personally believe that on the day of judgment, everyone of them will be made to atone for their bastardization of the faith.
Both Christianity and Islam have a concept of Heaven and Hell. Both also believe there will be a Day of Judgment at the end of the world in which everyone will be judged.
True Christians (the true servants of God) will go to heaven on Judgment Day.
Christians rest on Sunday because they officially believe God rested on Sunday.
Because that is the day that they believe that their sins were forgiven.
Christmas is celebrated by Christians and non-Christians because the majority of people believe in god and Jesus and they obviously will believe that, that was the day that Jesus Christ was born even though it was not the accurate day it was a guess and that's why its celebrated on December 25th.
