VioletSky 2. Is it Christianity where there is an old and new testament? I don't rely on my memory, if so was the new testament changed to reflect new societal norms or did the new testament change societal norms? Is it still subject to change? Can it be rewritten?
Yes, Christian Bibles are comprised of 2 parts - Old Testament before Christ was born, New Testament after Christ was born. Nothing added that I know of. However, one Christian faith has 7 additional chapters in their Bible (Sirach, Wisdom, Tobit, 1 Maccabees, Judith, additions to Daniel, and Esther). I doubt anyone except quite serious Biblical scholars give the whys a thought.
Various Christian faiths believe their Priests are allowed to give blessings, contested by others. One Christian Church finds it Biblical that they are the Church of the Bible (Matt. 16.18), obviously not believed by others.
Only God knows all answers, He will sort things out.
3. Some religions, there seems to be a disconnect. Some churches actively campaign against what they consider a sin, like homosexuality whereas others except anyone and would not preach homosexuality as a sin. How can this be? Would it benefit religion as a whole to become more progressive and accepting? Not just for itself but for its followers.
I believe Biblical belief teaches "love your neighbor as yourself" "judge not" "do unto others as you would have done to you" "glass houses, not throwing stones" "removing the plank from your own eye before worrying about the speck in another's eye" - His teaching cover human sins. Always forgive others, let God be the judge, it's not for humans to decide.
I believe God has no problem with homosexuality, perhaps just homosexual acts, premarital sex, divorce - but He is not clear, so I revert to not judging for anyone other than myself.
