Of course not! That has been the idea promoted by who concluded that fulfill means abolished. If fulfill in Mat. 5 means abolished then so does Acts 3:18 But those things, which God before had shewed by the mouth of all his prophets, that Christ should suffer, he hath so fulfilled.So Jesus abolished all the prophets said.
Truncating Matthew 5:17-18 into a meaningless sound-bite leaves you ignoring the fulfillment the
Greek pleroo, indicating Jesus' intent to bring the Mosaic covenant to consummation in His expiatory sacrifice and atonement. Besides this, you're describing your own position, as you're now unable to reconcile your latest complaint with your opening statement:
I have just discovered that Jesus abolished the entire Old Testament, not just the law.
For you, Christ's fulfillment of the spring feasts culminating in bringing salvation to the Gentiles on Shavuot (Pentecost) never happened. For you, there isn't going to be a second advent, for Acts 1:11 derives God's promise to return from Zechariah 14:4. For you, the fulness of time has never and will never come, and as a Gentile you remain and will ever remain forever estranged from God:
Ephesians 2
11 Therefore remember that you, once Gentiles in the fleshwho are called Uncircumcision by what is called the Circumcision made in the flesh by hands 12 that at that time you were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world. 13 But now in Christ Jesus you who once were far off have been brought near by the blood of Christ.
There is no such thing as "now" in a view that rejects Christ's propitiation.
Calvary didn't do anything within a view that dismisses Christ's promise to fulfill everything in the Law and the Prophets. Don't bother bringing up heaven and earth passing away, as that won't ever happen because nothing will be fulfilled. Yours is the most miserable view that comes from forcing your Adventist doctrine into Scripture.
