Among orthodox churches today, there are generally 3 categories:
1. Gospel Believing
2. Gospel Proclaiming
3. Gospel Centered
Such distinction would not have been necessary if churches do not falter.
They are all good, if taken together as a whole.
The first one: If only Gospel Believing and not proclaiming (preaching to outsiders) and Gospel Centered (living biblically, godly, always giving glory to Christ, etc.), then such churches, though still hold firm to orthodox teachings and doctrines, are about to fall, close down or mutate into heretical form.
The Second one: If it is Gospel Proclaiming, it already has firm doctrinal ground. But without being Gospel Centered, it does not grow rightly with God, soon, its doctrine would go off course to reducing itself to only a Gospel Believing church or focusing in numbers, memberships, by adhering to charismatics or worldly business tactics.
The Third is the best option, for it already comprises the other two.
I put CCCNY in the 1st category; while Redeemer the 3rd. Of course, I do not demand perfection in qualifying for any category. It is based on what they themselves admit in their own goals, their own visions.
