I am just wondering what the Catholics here think of God answering the prayers of people in other denominations and religions? If the RCC is the one true church, then why would He see fit to answer the prayers of those of other churches and religions? If everyone outside of the RCC is so wrong, why does God bless them? Maybe He sees past the lines of division of faiths and chooses to bless His children because they are His children! Do we only bless our children if the love us? NO! We bless them and care for them because they are our children and it is our place in life to care for them

Annie, Jesus told the Pharisee, “…man was not made for the Sabbath, but the Sabbath for man.” - parapharse. Likewise, man was not made for religion, but religion for man.
Look at all the organized religions in the word, Catholicism, Protestant, Muslim, DLS, Jewish, Hindu etc etc.
Then look at all those who founded those religions, God the Father formed the Jewish religion and Jesus His son, through the Last Supper offered a very personal and intimate relationship with the believers, which many Jewish people rejected and therefore Jesus offered it to the gentiles and it has spread througout the world.
Luther, Calvin, King Henry VIII created protestant religions. Brigham Young formed the LDS, and the list of “men” who have defined their own brand and created all other religions.
You are correct, God will save whom God will save as He is not limited by religion in offering His saving graces. However, if in reading the bible (Matthew Chapter 16) you can see the roots of the Catholic faith - as founded by God in His personal selection of Peter - “. . .Blessed are you Simon . . . no mere man has revealed this to you, but My heavenly Father.” And as decared by Jesus “…I for My part declare to you, you are ‘Rock’ and on this rock I will build My Church, and the jaws of death shall not prevail against it.”
Therefore, why would you chose to belong to a Church formed by a man/men to pursue the wisdom, knowledge and understanding of God, when you can belong to the Church organized by God the Father through His Son Jesus?
