Orson Pratt, Journal of Discourses 18:172; “But as there has been no Christian Church on the earth for a great many centuries past, until the present century, the people have lost sight of the pattern that God has given according to which the Christian Church should be established, and they have denominated a great variety of people Christian Churches, because they profess to be. They say, “We have built chapels unto the name of the Lord; we call our Churches Christian Churches, they are called the Church of Christ, St. John’s Church, St. Paul’s Church, St. Peter’s Church, and after others of the ancient Apostles;” and one who had never studied the pattern which God has given of the Christian Church would almost really believe that they are Christian Churches.” – Salt Lake City, March 26, 1876
Matthew 28:18-20; “And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. 19 ¶ Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.”
This passage from the Bible serves as our ticket of authority to go out and preach salvation to mankind. The Christian church has been here without interruption since Christ instituted it.
