Protestantism is largely from Hell. It's true. Protestantism gives people a very emotional experience and it's all just emotion driven. Having said this, I do think some innocent people are in protestantism.
Protestantism denies Our Lord His very own Church. All of it.
Protestantism sneers at Our Lady who was chosen by God to bring Our Lord into this world.
Now, if Protestantism had developed side by side with the Catholic Church from the very days of Our Lord then they would have a case but Protestantism popped up during the Renaissance and was led by rebellious men.
Protestantism tries to place a limit on Our Lord - I saw a sign outside of some protestant house of ill-repute that said "The Word Alone" - well, Our Lord never said anywhere that we are to just obey the printed word that wouldn't even be available to the average man for 1600 years or so after Our Lord's Death and Resurrection so having said this, Our Lord could never be "The Word Alone" because that places limits on Our Lord.
Protestantism, if you break it down, is from Hell.
