Christians: Are other Christians your allies or your enemies?

Either way I am to love them. I have a hard time being allied with peple who dont eat the flesh and blood of our lord as he dirested, plus I do not trust anyone who does not go to confession on a regular basis, also when I was with the fundies I heard, but did not engage in the catholci bashing prior to the weeklhy prayer breakfasts, you know that the pope is the anti-christ, and blessed mother, well let's just say something less than a virgin, but it's the lack of obeidience the lack of regular confession and communion, why aould i wnat someone who is dead as an allie, my job is to hel p them, I do that by telling the truth.
