I certainly reject anyone who tells me that I am not a Christian, nor is anyone who is a Roman Catholic. What arrogance, what ignorance, what malice.
You can try to dissuade Christians from loving and trusting Jesus, but it really won't work. You can try to call us from the Word, but our Lord's "It is written" will remain our motto. You can tell us we mustn't care about the lost, mustn't care aout folks whose false religions offer false hopes and false comfort, but Jesus won't let us.
Sometime, some quiet time, just you and God, really think through the Scriptures in the thirty-three questions
And if you find that you can't even bring yourself to do that, at least some time, try to figure out why. If the Word didn't scare you, repel you, threaten you, why would you not want to think about it? Be honest; just you, and the God who can't be fooled.
