First of all, one can not change from Catholic to Christian because a Catholic is a Christian. But, if by Christian you are referring to a "protestant" then yes, it is a sin punished by excommunication; and, if unrepented before death, would involve one's damnation. This is called formal heresy (as opposed to material heresy) and is very serious.
from Modern Catholic Dictionary by John A. Hardon, S.J. Doubleday & Co., Inc. Garden City, NY 1980
Heresy. Commonly refers to a doctrinal belief held in opposition to the recognized standards of an establish system of thought. Theologically it means an opinion at variance with the authorized teachings of any church, notably the Christian, and especially when this promotes separation from the main body of faithful believers.
In the Roman Catholic Church, heresy has a very specific meaning. Anyone who, after receiving baptism, while remaining nominally a Christian, pertinaciously denies or doubts any of the truths that must be believed with divine and Catholic faith is considered a heretic. Accordingly four elements must be verified to constitute formal heresy; previous valid baptism, which need not have been in the Catholic Church; external profession of still being a Christian, otherwise a person becomes an apostate; outright denial or positive doubt regarding a truth that the Catholic Church has actually proposed as revealed by God; and the disbelief must be morally culpable, where a nominal Christian refuses to accept what he knows is a doctrinal imperative.
Objectively, therefore, to become a heretic in the strict canonical sense and be excommunicated from the faithful, one must deny or question a truth that is taught not merely on the authority of the Church but on the word of God revealed in the Scriptures or sacred tradition. Subjectively a person must recognize his obligation to believe. If he acts in good faith, as with most persons brought up in non-Catholic surroundings, the heresy is only material and implies neither guilt nor sin against faith. (Etym. Latin haeresis, from the Greek hairesis, a taking, choice, sect, heresy.)
They see prostitution as a sin, as do most christian religions. The bible calls prostitution a sin.
It depends on your religion. If you are Buddhist or Atheist , then its not really a sin for you. Its not sin for the Islamic religion but you really shouldn't cheat though. But it is a sin if your Catholic or a Christian. I am a Catholic myself. Cheating and Stealing is wrong, therefore it is a sin.
Its not just "Christian" living these days, because evil lurks in every religion except the true catholic church. Being a devout Catholic includes following the commandments, receiving the sacraments, praying often, and refraining from sin especially mortal sin.
Judaism does not have the concept of Original sin. This is a purely Christian concept. It's purely a Catholic concept, anyone who knows the bible and knows what it means to be a Christian knows that the Catholic Church and their beliefs don't fit into that definition. Original Sin is one of those beliefs Ezekiel 18:20 in plain terms says everyone is responsible for their own sin.

M. Shadows is not a Christian, but he is Catholic. A Catholic IS a Christian. Catholicism is a denomination of the Christian Church. Hope that helps.
Well, Catholics are Christians. The word "better" makes the question very subjective and will change depending on who you ask. A Catholic will say it is better to be a Catholic but being a Christian who is not Catholic is the next best thing while a Christian who is not Catholic will say the opposite.
No. Brandon Heath is a Christian, not Catholic Christian.
