My Grandmother was also Baptist as I was raised Southern Baptist. She was a very devout and holy woman and I have sincere confidence that she is in heaven. Catholicism does NOT teach that Protestants are going to hell, only those who go to hell are those who by their own free will choose NOT to follow what God, by His grace, revealed to them as truth; those who are in mortal sin at death. Essentially everyone has a chance at heaven whether Catholic or not if they trust their lives to Jesus Christ or to what they know to be true and follow what they have been shown as the truth from God. God is a just God and won’t condemn anyone who is not culpable of what he/she doesn’t know for sure to be true. However, it is easier to be saved being a Catholic since the Church has the fullness of divinely revealed truth and keeps us on the straight path of faith and morals.
Luke 12:48 says…
" Much will be required of the person entrusted with much, and still more will be demanded of the person entrusted with more."We are all accountable to what we know whether it is great or small. Protestant Christians who live a life of faith in Jesus, hope, and love and don’t know they are compeled to become Catholic still receive eternal life if they obey what they knew to be true, since they didn’t know they were obligated to become Catholic. God only accounts us culpable of what we “know” to be true. It’s NOT the Church’s job nor anyone else to judge the state of a persons heart at death, since we all have free will and can turn towards or away from God in this life. Catholicism simply says that it has the fullness of divinely revealed truth, so to be Catholic is the easiest way to acheive eternal life.
