Dr. Scaer the Elder, one of my seminary profs and an authority on Christology, said in class once something that at the time was hilarious and absurd,
God is the biggest heresy of all!As I think back now on that now, I can see how scarily accurate that striking statement really is. The problem is not "God" as it is, but indeed is "God" as He is turned into "god". It happens when God is seen merely as Almighty, Awesome God to the exclusion of Jesus Christ. This is a problem. And this heresy, if you'd like to call it that, is rampant in churches throughout the U.S. and I see it more often than not turning up in the church growth movement.
Listen to the way people talk and pray. If there is more a talk of "God" than of Jesus Christ, there is indication of a huge problem. God then becomes merely deistic, or theistic (apparently I must use both for my Latin and Greek etymologists) and is not found in Christ Jesus. Truly the fact remains that God is only revealed to us in Christ Jesus. We can know God no other way, for Jesus himself said, "No one comes to the Father, but through me." There must be a clarity of the Triune God focused clearly through the lens of Christ. Without that any talk of God is truly heresy, and clearly so when Christ and His redemption gets pushed to the side. The truth that Christ is central to Christianity must be seen. Without Christ, "God" (or god) is truly a sinful belief.
