You're imbibing in what Scriptures call the Doctrine of Devils. My friend Gerry Matatics used to attend Charismatic meetings in which he would recite Psalms in Hebrew. Of course others would come up and translate for them. It's amazing how the Holy Spirit doesn't recognize his own words.
I suggest you go hear Gerry if he comes to your town or you can check out his conversion story of how the Bible convinced him that the one, true Church of Christ is the Catholic Church.

It seems you know nothing of Church history except charismatic revisionism.
You're following practices that go no further than 100 years back and have their origins in Wisconsin.
As far as believers who don't join the Catholic Church goes, if they don't join, they will go to Hell. It's that simple. If they don't believe in the Church that Christ established here on earth, then they are not believers except in the Devil making himself into an Angel of Light in order to fool them with false versions of Christianity.
They are lost as well if they are not saved according to Christ's will.
