Dispensationalism is indeed heresy. It wrongly divides the Scriptures as God dealing differently with man according to different dispensations.
Brother, know this, I respect you more than any person in this area, but, that is simply your vp.
A "dispensation" in the simplest definition, is nothing more than an unspecified length of time.
It can be shown from scriptures that prior to Jesus, there were a few "covenants" God made with Israel. And none of the "covenants" negated the previous ones.
For example, the Adamic Covenant/dispensation. (Considered 2: Edenic/Adamic)
From the time God created Adam, until Noah, this is one "dispensation". God made a covenant with Adam. When Adam sinned and was driven out of the Garden, then comes the Adamic curses.
Between Adam and Noah, that "covenant/curse" stayed. After the deluge, came the Noahic Covenant (dispensation).
The "covenant" God made with Noah had better promises, sealed by God's "rainbow". Did the "covenant" God made with Noah, disestablish the Adamic covenant? Evidently not. Man and woman still reproduce. We still till the ground for our beard. We still live by the sweat of our brow. Did God deal with Noah the same way He dealt with Adam?
From Adam to Noah was one "dispensation". From Noah to Abraham was one dispensation. etc, etc.
It makes Israel and the church two different entities dealt with in two different manners.
That, I will not argue against. You are 100% correct.
It is founded and grounded on a eschatological system that is at best a theory. It makes you jump through countless hoops of proof texts in order to support it.
Again brother, your viewpoint. As a matter of fact, all "eschatology" depends on the individuals "countless hoops of proof texts in order to support it".
When speaking on "eschatology" even Jesus (the God-man) said He didn't know.
Absolutely nobody, has an eschatology that is 100% correct except the Lord God Himself.
I am sorry but you simply do not start with an eschatological system and then build a theology around it.
We just can’t compromise because it is so popular and people we love adhere to it. We must call a spade a spade.
Here again, that but not necessarily "dispensationalism", is not the only "theology" that starts with a singular viewpoint and builds around it. What you see as heresy, to some groups, is truth. You and I agree there are some things Catholicism teaches that you and I regard as "heresy", but to them, its truth.
I'm sorry brother, I love you to death, respect the ---- out of you, but in regards to dispensationalism, we'll always be separate.
You should visit the GT area, especially the "Covenant Theology" area, since you are so strong in this area.
God Bless
Till all are one.
