I'm in the same boat as you man, my view is Jesus died on the cross for sinners, of whom i am the worst.
People always want to split hairs and lose sight of the whole point of christianity. When Jesus walked the earth the pharises and saduses did the exact same thing, trying to cross every T and dot every I and they lost sight of the whole point of religion, and never even acknolage Jesus Christ as the try son of God.
Could it be wrong to celebrate Easter and Christmas? maybe but i think that you have to look at the reason for celibrating it and look into your own heart. Are you celibtrating it for greed or to acknowledge the life, death and resurrection of Jesus? The same way i look at church, do you go because your told and think you can receive salvation from it? or because you want to give God his day of praise
