One of the apostles, John, saw demons cast out in the name of Jesus by one who did not belong to the circle of disciples and forbade him to do so. On recounting the incident to the master, he is heard to reply: “Do not forbid him … For he that is not against us is for us” (Mark 9:39, 40).
This is a topic of great current importance. What to think of those who are outside, who do something good and show signs of the spirit, yet without believing in Christ and adhering to the Church. Can they also be saved?
If some of our progressive brethren can apply Mark 9:39-50, I suppose the Catholics can use it to talk about non-Christians, according to their definition. Just goes to show that, when you want to ignore the original context of a passage, anything goes, whether it be a Catholic interpretation or a wayward brother.
