There was a question asked of Our Lady in October 1981 which was: Are all religions the same? Our Lady answered: "Members of all faiths are equal before God. God rules over each faith just like a sovereign over his kingdom. In the world, all religions are not the same because all people have not complied with the commandments of God. They reject and disparage them."
The difficulty that some Catholics have had with this answer is based on the belief that the only salvation is within the Catholic Church. But the Catholic Church does not believe this. In fact, Vatican II in its Dogmatic Constitution on the Church "Lumen Genitum" says this: "Those also can attain to salvation who through no fault of their own do not know the Gospel of Christ or His Church, yet sincerely seek God, and moved by grace strive by their deeds to do His will as it is known to them through the dictates of conscience. Nor does Divine Providence deny the helps necessary for salvation to those who, without blame on their part, have not yet arrived at an explicit knowledge of God and with His grace strive to live a good life."
It is a great privilage to be Catholic and I love my faith. I share my faith through my actions and words whenever possible. But as Matthew 7 says "Judge not, that you may not be judged". It is not up to us to decide who goes to Heaven and who does not by their faith.
