I'm a "catechumen", so to speak.
I received a doubtful Protestant baptism.
I don't consider 99% of non-Catholic "Christians" Christian at all**.
They are perhaps practicing a Christian-ism, but they are not Christians.
Christian literally means "Christ one"... like Christ. That comes from the sanctifying power of the Holy Ghost, which non-Catholics cannot be at all sure to have.
** The people I know whom I consider "Christian", yet not Catholic, are a VERY, VERY few who are in the Protestant/evangelical world, yet not beholden to their traditions. These people are genuinely interested in pursuing the truth wherever it takes them. I am aware, as are they, that it is no simple task to simply leave the Prot world and go "be Catholic", what with all the confusion and danger to souls presented by the Conciliarists in Newchurch.
Yes, I know I'm choosing a "liberal" definition of the word "Christian" here, but I dare say it is MUCH better to see these people as humble, sincere and on their way to cooperating with Divine grace than it is to either leave them in their former errors or condemn them altogether because they have not arrived yet.
All that to say this: I'm not Catholic, "officially", yet. Am I a Christian at all?
