Go to any church, any one at all. The only difference is that you will not be participating in a fraudulent service as you would if you went to a "messianic Jewish" congregation. "Messianic Jews", as anyone with half a brain knows, are Christians who refuse to call themselves Christians and instead fraudulently call themselves Jews. They are an insult to both Judaism and Christianity and should be universally condemned for religious identity theft as well as fraud. No Jew on earth considers them in any way Jewish. Most Christians, except the more gullible ones, also know that these people are not Jewish.
