Bible believers: Do you agree with each and all of the following?

You come up with the best questions! Luckily, most people don't follow the Bible too closely. If one followed the teachings attributed to Jesus in a general sense (as I do), ALL are welcome to participate in his church, no exclusions. This would mean that same- couples should be able to marry in the church. I wonder if the "Christians" that follow the old testament realize that they are really "Jews for Jesus?"
