I have a close Orthodox friend and we always talk about our faiths with each other. For example, take contraception… I can’t help but feel compelled to tell him his willingness to use contraception is wrong and then I want to tell him he should really check out Theology of the Body… etc. We are close enough friends that we can talk about these kinds of things without each other getting offended. It is at this point I start to feel like I am sort of evangelizing him a bit… (I just love talking about my Catholic faith). I just wonder if, as a Catholic, when the opportunity arises, should I promote Catholic truths to him that the Orthodox don’t have? Or just leave him be with the attitude 'you be a good Orthodox, I’ll be a good Catholic"?
