Any true Church of God will keep the seventh day Sabbath and the Passover. The first three chapters of Revelation cover the history of the Church of God. There are seven eras over 2000 years.

Revelation 3:7 [ The Faithful Church ] “And to the angel of the church in Philadelphia write, ‘These things says He who is holy, He who is true, “He who has the key of David, He who opens and no one shuts, and shuts and no one opens”:

The Key of David unlocks the Bible. Find he who has the Key of David and you will find the Church of God. Isaiah 22:22 also mentions the Key of David.

Google the key of David and the link to God's Church will come up, along with the false imitators.

I believe the Sabbath is a day of rest which if observed is keeping the Sabbath holy, but is there any orders from God that the services should be held on Saturday?

The apostles started their preaching on the first day of the week.

So I believe there are two falsehoods, the first being that a Sabbath keeper must attend church on the Sabbath and the second is the Sunday Sabbath.

So, only under the law Judaizers are the only ones who have “the key of David?”

Since we are in New Testament times, I am inclined to believe that King David’s greater son, Jesus Christ, has has a little to do with that key.
