However, it would be entirely foolish to toss aside accumulated knowledge about the path to salvation, just because you think you can read the Holy Scriptures, even though you are living 2000 years later, in a culture which is completely foreign. The scriptures were compiled with an interpretation in mind, and can't just be read using modern definitions of words.i'm absolutely not saying you shouldn't go to church, btw. i'm from a muslim country, i'd love to have a church, to have people in my life who love Jesus. what i'm saying is that, God, from the beginning was against the idea of being tamed into a building. our bodies are the temple of God. it's a wonderful thing to come together in the name of Jesus and sing praises to the holy name of God, but if redemption is attached to it being a necessity, this is antichrist. buildings are made with hands and the entire hierarchy is us, under Christ, who is under The father
