The true Church is the one that continues in the traditions, teachings and practices of the New Testament Church. Our Bible study aid booklet The Church Jesus Built details the transformation and corruption by reformers of many teachings given by Jesus Christ to His disciples. God's Church rejects the doctrines men have added or changed, and it holds to “the faith which was once for all delivered” (Jude 3).
An important tenet of Jesus' teachings was the gospel of the Kingdom of God. The role and work of the Son of God is central to the gospel. However, most churches preach only a message about the person of Christ, saying much about His role as Savior but little about His role as King. In other words, most churches do not preach the gospel that Jesus did. Jesus came as a special Messenger (Malachi 3:1 Malachi 3:1Behold, I will send my messenger, and he shall prepare the way before me: and the LORD, whom you seek, shall suddenly come to his temple, even the messenger of the covenant, whom you delight in: behold, he shall come, said the LORD of hosts.

The true Church will also be preaching this gospel to the world as a witness (Matthew 24:14 Matthew 24:14And this gospel of the kingdom shall be preached in all the world for a witness to all nations; and then shall the end come.

Another key in identifying the true Church is the correct day of worship. Jesus customarily observed the seventh day, the Sabbath (Luke 4:16 Luke 4:16And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.

Scripture reveals that the Sabbath is a perpetual sign or an identifying mark of the people of God (Exodus 31:12-17 Exodus 31:12-17 12 And the LORD spoke to Moses, saying, 13 Speak you also to the children of Israel, saying, Truly my sabbaths you shall keep: for it is a sign between me and you throughout your generations; that you may know that I am the LORD that does sanctify you. 14 You shall keep the sabbath therefore; for it is holy to you: every one that defiles it shall surely be put to death: for whoever does any work therein, that soul shall be cut off from among his people. 15 Six days may work be done; but in the seventh is the sabbath of rest, holy to the LORD: whoever does any work in the sabbath day, he shall surely be put to death. 16 Why the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. 17 It is a sign between me and the children of Israel for ever: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.

The Church Jesus Built discusses these topics more thoroughly. It shows the beginnings of a counterfeit Christianity in the first century. Several books of the New Testament mention false teachers infiltrating the Church with corrupting ideas. They combined bits and pieces of pagan religions with Christian concepts and convinced many to follow their ways. Satan has taken great advantage of these circumstances (2 Corinthians 11:13-14 2 Corinthians 11:13-14 13 For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
14 And no marvel; for Satan himself is transformed into an angel of light.

The Bible study aid explains the doctrines and practices of the early New Testament Church of God, so those who would like to find it today can do so.
