The Holy Church of Christ

Earliest mention of them I've found is the mid 1970s. Do you suppose they're a schism of the Churches of Christ?

 

From one church's website's "What We Believe" page:

Church Covenant

Having given ourselves to God, by faith in Jesus Christ, and adopted the Word of God as our rule of faith and practice, we now give ourselves to one another by the will of God in this solemn covenant.

We the Holy Church of Christ represent the old Church of Christ that He built on this rock, the oldest church, and the gates of hell shall not prevail against it.

We also believe that Jesus Christ is the Son of God who shed his blood on the cross of Calvary for our sins. He is the door.

St. John 3:5-7 “Jesus answered, verily, verily I say unto thee, except a man be born of the water and of the Spirit he cannot enter into the Kingdom of God. That which is born of the flesh is flesh and that which is born of the spirit it spirit. Marvel not that I said unto thee, ye must be born again.”

St John 10:9, “I am the door; by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.”

We believe that the Authorized King James Version of the Bible is the true guide with nothing added to it or taken away.

We believe that water baptism is the answer of a good conscience toward God. We baptize in water in the name of the Father, the Son, and the Holy Ghost, which the Lord commanded us to do.

We believe in establishing Holy Churches of Christ and setting in order the things that are wanting, and ordain elders and deacons of the church.

We believe that the church should pay tributes to the ministers of God.

We believe that all members who come into this church shall be subject to the Bible for it is the guide of the Church.

We believe that there should be no schism in the body, but the members should have the same care one for another.

We believe that the Bible is the revealed Word of God, and that Holy men wrote it when they were moved on by the Holy Ghost. We believe the Bible is revealed to His people by the Spirit of God and the Bible is not the spirit, but the sword of the Spirit.

We believe that all things must be done in love, in preaching of the Word, being instant in season and out of season, reproving, rebuking and exhorting with all long suffering and doctrine.

We also believe that if a brother be overtaken in a fault, we that are spiritual should restore such a one in love and in the spirit of meekness.

We believe that all members should be diligent in attending the worship services of the church according to Hebrews 10:25. “Not forsaking the assembling of ourselves together, as the manner of some is, but exhorting one another; and so much the more, as ye see the day approaching.”

We will never be governed by anything that is contrary to the Authorized King James Version of the Word of God.
