church is suppose to be more than that.
You nailed it.
Find somewhere where people still love the Old Testament and haven't thrown out the 4th commandment. Observe Sabbath, Biblical feast days, and eat the way God wants you to. This is how the early believers worshipped before the hellenized pagan influence took over after the apostles died off. (this takeover had already begun in Paul's time as Paul mentioned to Timothy)
May your search bring you much peace and fulfillment.
How does your church like your denial of the divinity of Christ?
