No, this is true for those 100 years ago, and 1000 years ago. We are not waiting for some future event so this passage will at long last be true. It's true now, regardless of your denial.
I Suppose you could harvest the wheat of the field before the wheat is ripe, and fruitful but it would defeat the purpose of planting the seed in the first place. This is why Jesus used the analogy of the wheat harvest, and the early and latter rain to describe HIS timing and how His chiurch would GROW in the field and become fruitful. So no the early church did not have the full revelation as the Holy Ghost the Spirit of Truth continues to reveal Christ to us in His fulness. (John 16:13) To claim that a finite mind can know all there is to know of an infinite God is Hubris of the mental kind. There is SOOO much you are missing out on, and you do not even Know it.
