The Mormons have a prophet too
As the Catholic church has human leaders that are both saints and sinners, and yet The Catholic Church continues to survive and spread the Good News. Could we do it better? Yes, and it takes time to bring people to understand and accept God's gift of Love to us and return their love to God and our neighbor. Do all Catholics fully understand and accept God's Love? Probably no.
What is the good news Rome spreads ?
Feel free to attend a Catholic Mass so that you can learn about the Good News.
