***That's the problem with major religions. They each preach that all the others will go to hell. ***
Not quite! While the Catholic church says that IF YOU BELIEVE IT TO BE THE TRUE church, but do not embrace it, you will be lost, it also says that you must follow your conscience. We all start from different points and have different influences in our lives.
That may be the official position of the Catholic Church, but it wasn't always so. Nor is it the official position of many Protestant branches of the religion.
Nearly all branches claim to be the one true one with various bad consequences for the ones who refuse to agree with them.
Which is heresy: "Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me." John 14:6 (emphasis mine)
