Justin Childers (Cross-Eyed) came across this in his reading.
“We have even heard it asserted that those who lived before the coming of Christ do not belong to the church of God! We never know what we shall hear next, and perhaps it is a mercy that these absurdities are revealed one at a time, in order that we may be able to endure their stupidity without dying of amazement” (Vol. 15, 8).
Keep in mind, dear readers, that when Spurgeon said this, dispensationalism was an innovative doctrinal position and interpretive method put forth by John Nelson Darby. Read this through Spurgeon’s eyes and time frame, not the 21st century glasses in which dispensationalism is the dominant theological view in western Christianity.
What is telling to me is that the NT authors violate the interpretive method of dispensationalism. They repeatedly apply promises given to Israel to the “church”. The Letter to the Hebrews is among the most troublesome for dispensationalists. One passage in particular that throws a serious monkey wrench into the idea is the very last verse of chapter 11. The numerous Old Testament saints listed in the “Hall of Faith” found there are not complete without the Jewish Christians (and us) to whom the letter is written. This simple notion undermines the notion of a two different peoples of God, namely Israel and the Church (both Jew & Gentile). This interpretive method is an absurdity precisely because it violates the Bible’s method of interpreting itself.
btw: I gather my info on dispensationalism from a long history of interacting with them, having once been one, and recently reading Charles Ryrie’s Dispensationalism Today. A bit dated but probably the most succint description by an advocate of traditional dispensationalism prior to the advent of progressive dispensationalism.
