John Bunyan couldn't have said it better! Glad to see you!
I am 100% convinced that the Catholic Church has the fullness of Truth. But, if what the Church teaches becomes an obstacle to someone knowing and serving the Lord Jesus Christ because in their hearts they truly are not able to believe some of those doctrines I would rather they became good devout Protestants than remain luke warm Catholics who might even feel hostile towards the faith.
I know there are Catholics who disagree with this, but I believe when we find what we are convinced in all aspects is the Truth we must follow it. If a person believes what the Catholic Church teaches is a lie and a barrier to Christ it would be a sad thing for them to stay.
