Not silly at all. The only church I belong to is the body of Christ, the church of God. I'm sorry if you're having trouble with this distinction, but my allegience is to Christ alone. The United Church of God has beliefs that closely match my own. That's why I attend services and fellowship there. If their beliefs change, I would leave. And it's not "Armstrong" material. It's material publicized by Armstrong, but it's been around for a long time. If you doubt me, name one doctrine on United's website that you think was created by Herbert Armstrong and I'll cite proof of it's existence before Armstrong.
I understand you can/will leave. This started about whether Armstrong was the founder of your church, or the founder of the church your church branched off from.
From the UCG website:
Many of the current ministers and members of the United Church of God were once members of the Worldwide Church of God, a nonprofit corporation under the leadership of Herbert W. Armstrong until his death in 1986. A subsequent unwarranted shift toward nonbiblical practices and beliefs led numerous ministers and members to leave the fellowship of that organization.So, this is what I meant. I'll rephrase it: The church you currently attend has many current ministers and members who were members of the WWCG which was led by Herbert W. Armstrong.
