Yes that would be a great idea and most needed.
Dont forget all the Christian Messianic Israelites & Messianic Jews also keep the 7th day Saturday Sabbath. There's at least a good 30 million 7th day keeping Christians in the world, like the bible said we would be a remnant.
I dont fit under the catergory of 7th day adventist because that's only one denomination of it.
Ya there's 1. Church of God, 2. United Church of God, 3. SDA, 4. SD Baptist,5. SD Evangelical like St Peter's Cathedral in Hawaii, 6. Messianic Israelite, 7. Messianic Jew, there's 8. Covenant Church of YAHWEH, 9. Assemblies of YAHWEH, 10 The Christ's Assemblies, 11. Christian Israelites of no denomination, 12. and hundreds more independent churches that changed over from Sunday to the 7th Day which I could list all day long like Restoration Ministries, Open Bible Ministries, Sacred Truth Ministries, Church of Israel, Laporte Church, and a great deal many more which dont fall under any of those denominational categories and teach & worship on the 7th day Sabbath.
