Knights of Columbus and Masons?

I wouldn't say that the 2 don't get along. We have marched in many parades together around here. The only big difference as I understand it is that the KoC is Catholic-based and the Masons are non-denominational. We take just about anyone. DeMolay is kind of like the Masons youth group. The next logical step for most is joining the Masons. I also don't think that there is any problem with a catholic joining the Masons, we have many catholic brothers in my Lodge. I hope this helps.
