UCG had this up on their June 1, message from Rick Shabi:
The New Testament Church, headed by Jesus Christ, had its “beginning” on Pentecost in A.D. 31, when God poured out His Holy Spirit on the 120 who were gathered together in “one place and one accord” in obedience to Him.
The corporate entity of the United Church of God, an International Association, had its beginning on the day of Pentecost more than a quarter century ago, as heresy infected the Worldwide Church of God and that organization departed from God and His truth.
The United Church of God continued in the truth and the “faith once for all delivered to the saints.” We are not a new Church that began in 1995, we are the continuation of the Church that was founded by Christ, still led by Him as its Head, and striving to fulfill the commission He gave in Matthew 28:19-20. Together, we are all part of His Church and His work.
How can it be that every single one of the splinter groups claims that THEY and THEY ALONE are the “faith once for all delivered to the saints” and yet none of them get along with each other or even hold the same teachings and doctrines? UCG is about as far from 1st-century Christianity as Bob Thiel and Gerald Flurry are.
If they are the "continuation of the church that was founded by Christ", where does that leave RCG, COGWA, PCG, COG7, and the rest of the splinters? Christ would be appalled at what the present state of UCG and what the rest of the COG's currently look like and act.
