I’m sorry Brandon, I misread your post.

Why are people being called into other churches besides the Catholic Church? I think it obvious that if a Protestant first tells them about the Gospel that they would enter into the church of the Protestant. That’s what happens with a lot of people who have never heard of Christ. That’s only natural. If an Evangelical church is all there is, then that is where converts will go.
Also, God desires that all men be saved. Any way that they hear the Gospel people are going to respond to the movement of the Holy Spirit to accept Christ. That doesn’t automatically mean they will be getting the fullness of the faith in non-Catholic churches. Whatever they learn of Christ is a grace, even if it’s incomplete. All who are baptized with the trinitarian rite (in the name of the Father, Son, and Holy Spirit) who truly desire receive what baptism confers–God’s saving grace, are Christians. The Catholic Church considers all non-Catholic Christians to be imperfectly joined to the Church by means of their baptism.
No one should stifle those spreading the Gospel of Christ to others. There is nothing wrong with that and everything right with it. But, Christ also gave us the sacraments and founded his Church on Peter and the Apostles. Those who aren’t getting the full benefit of the sacraments and the Church’s authority are missing out on a great deal. Only those who come to see that the Catholic Church is truly Christ’s Church and still reject it are truly in mortal danger of going to hell. I imagine that about 99% of all non-Catholic Christians haven’t knowingly (with full knowledge of what the Church truly is) rejected the Catholic Church, wouldn’t you say? Most Protestants I know or that come here have a lot of misconceptions about the Church. God will not hold them accountable for what they didn’t know, but only for what they did know and then rejected.
