I honestly know little about the Freemasons, but cannot see any reason why they would reject anyone. In contrast, I can see more resentment or distrust from Catholics in general on the Freemasons than them distrusting Catholics. I grew up Catholic, but no longer am because I don't agree with all that they preach or stress along with my own personal experience. On a side note I don't hate the religion or Catholics either.
That is a typical religious response... lol
