I was a Roman Catholic and converted to Anglicanism for this very reason. I am not scrupulous about sin but the whole concept of mortal vs venial sin was an anathema to me - it seemed to make God very harsh indeed. I love the responses that Tiffy and Invictus posted about being a disciple of Jesus Christ. Make the move - all you have to lose is all that guilt and oppression!
A person once close to me was taught in her church as a child that, "The Roman Church is the one true Church". I guess she was not the only one in Eire who believed this to be true. She was also told that salvation could only be found in the church, which she naturally assumed meant THAT church, from THOSE priests, in THOSE buildings. She was even told "Don't go into a church with a cockerel weathervane on its spire. It's not a proper church, only go into one that has a cross on it.” She was also told that she needed to go to church regularly to have all her sins forgiven. So all in all it added up to "You'll go to hell if you leave the RCC". What some church teachers IN a church might teach children, is not necessarily the same as what that church officially teaches adults. .
What would be the Anglican impetus to convert a Catholic? I thought Anglicans considered Catholics to be true Christians, and a part of the Only, Holy, Catholic and Apostolic Church, as understood by Anglicans?
Holy catholic, not Roman Catholic. There are some Holy catholics in the Roman Catholic denmonination, for sure. .
