For over 70 years, in the zealous mindset of the Churches of God, when it comes to prophecy, they have been trying to fit their predictions into reality like trying to fit a square peg into a round hole. They have never even come close to even beginning to have a handle on any kind of accurate prophecy in any of their major predictive theories. Not even once.
Which is honestly saying a lot, because their entire theological foundation hinges only on their predictions of prophecy being correct. Their claim to fame is that they, and only they, have the keys to the Kingdom of God, and that through their understanding of their identity as "spiritual Israelites", then suddenly everything was supposed to have fallen into place. This is the very thing that all ex-members, living or dead, of the Church banked their lives on - that the Church had a mystery long solved, evidenced by their correct interpretations of prophetic understanding.
From their claim that a large part of the Bible is nothing but prophecy, to their literal interpretations of Revelation to the claim of theological duality in prophecy - their claims were the biggest part of their legacy that made the "glory years" what they were. It were these predictions that filled arenas and auditoriums with those who believed what they interpreted prophecy to mean. Who can forget their colorful images of Daniel, of Beasts - of Revelation images with the voice of Art Gilmore over brass instruments echoing their prophetic interpretations? The biggest gamble of any Church of God member's lives was the gamble that the Church knew what they were talking about. The only problem? Enough time has passed that any logically thinking person can know with full certainly that every thing they ever said about prophecy has turned out to be absolutely, categorically, and blatantly false. Their prophetic interpretations cannot be defended, and any belief in their prophetic interpretations today can only be attributed to an acceptance of lies and an inability to renounce what must be renounced, if truth is the yardstick one measures by.
Chronological timeframes have been wrong. Predictions about people have been wrong. Predictions about world events have been wrong. Predictions about world leaders have been wrong. Every one - but that has not stopped certain zealots who believe they alone have the correct interpretation of prophecy from trying. Whether it's Bob, Dave, Ron, James, Gerald, Gerald, or Tom, Dick and Harry - without fail, their timelines end up being fantasies based on delusions of correctness. Truthfully, a five year old who claims to understand how algebra and calculus works can be trusted more than a Church of God minister who claims to know how prophecy and the Bible works. Plus, a five year old can be trusted more than any Church of God minister can. At least a five year old has the intelligence to be corrected when told he's wrong and listen to people who know more than he does.
If their entire construct of their entire religion - and we're talking about Armstrongism - is wrong, then how can one put any credit in anything that they talk about? Partly because of one simple comparison that every one of them makes - them vs. what they see "in the world". What the Armstrong Apologist sees in the world of Corporate Christianity to them is far worse then the failures of Armstrongism. They see what they view as idolatrous worship of false images, pagan holidays and symbols, sun worship, belief in lies such as Santa and the Easter Bunny, embracing of Jeremiah-like Christmas trees, and the rejection of Old Testament commandments they feel are in force. This is what they use to justify that they are "more correct" than "the world", even though in reality they are just as wrong, just in a different tangent. What they do not admit they are doing, however, is measuring everything in the mind of physical legalism, not in the mind of spiritual atonement and reconciliation with God in a pure heart in mind - which they think is impossible spiritually as they judge them physically based on what they think is unacceptable in the eyes of God.
Regardless of your opinion about the physical aspects of more mainstream Christianity, or however disgusted you are with some of the traditions and observances of the same, it does not change the fact that the Churches of God have been sharply condemning of others while dismissive of their own heretical problems. There can be no sugar coating it - lies, deceptions, delusions, and failed prophecies have been as big a problem with the Churches of God as they ever could be. And no amount of shifting blame to the problems of Mainstream Corporate Christianity as they see them will ever make that statement untrue. Untold harm and psychological damage has been the result of the lies and failures of the Churches of God's prediction addiction from people of all ages - from children to senior citizens, and all those who have ever listened to the lies of Herbert Armstrong and every splinter leader, from Dave to Bob to James, who in their self-righteous arrogance dares think they speak for God when the record is clear they only speak from their own minds, without one shred of credibility or reason to believe they could be right. Ronald Weinland himself has cemented the reality of what happens when one banks on Armstrong predictions for the record of Armstrongism for generations to come.
There is one thing about prophecy that we can know for sure is true in the Churches of God when it comes to the "sure word". That the only sure word of "prophecy" in the Churches of God is "False".
