The Early church was built by Jesus with his blood. We must find the same church as the Early church. Which one is that church among so many churches which are different each other? When we know what teachings were kept in the Early church, we can recognize true church. The most distinguishing teachings are the Passover of the new covenant and the Sabbath. Today, there's only one church in the world which keep the teachings above. It's the Church of God called WMSCOG.

The authentic church established by God must have the truth of the New Covenant. From the Old Testament times, God foretold that He would establish the New Covenant and those who practice the New Covenant would be His people. As it is prophesied, the New Covenant was established by Jesus, the incarnate God on the feast of the Passover. Then what is the New Covenant ? To put it briefly, the core of the New Covenant is the Passover, so the authentic church must have the truth of the Passover. And Jesus commanded us to preach it in the whole world until the end. There is only one church meeting this conditon, and that's the Church of God. Therefore, the Church of God is the church that God established and its founder, Christ Ahnsahnghong who restored the Passover of the New Covenant is God Almighty.

The Bible recorded that the early church that Jesus established kept following Jesus' teachings clearly. Nowadays we can not find the church like the early church except WMSCOG.

Amen.
We need to check what we are keeping for our salvation belongs to the words of God.
Is there a record of keeping the Sabbath in the Bible? Yes.
How about the Passover of the New Covenant? Yes.
Jesus and His disciples kept the Sabbath and the Passover of the New Covenant.
But, Sunday service and Christmas are not stemed from the Bible.
So, the World Mission Society Church of God which keeps what the Bible says is the genuine church that has salvation.
