OTWell, thank you. Now stop answering my questions and get back on topic.

My problem is that I don't believe fully that Jesus Christ is our Lord (the Messiah), so I'm not saved when I'm back in the conversation and I always find an atheist objecting my faith with rationality.

If you don't believe Jesus Christ is our Lord then how can you claim Catholicism is a Christianity? I, of course, don't think it is....but I'm wondering why you think Catholics are Christians if they believe they need a priest so as not to go to hell, instead of Jesus?
