"And he saith unto me, Write, Blessed are they which are called unto the marriage supper of the Lamb. And he saith unto me, These are the true sayings of God. And I fell at his feet to worship him. And he said unto me, See thou do it not: I am thy fellowservant, and of thy brethren that have the testimony of Jesus: worship God: for the testimony of Jesus is the spirit of prophecy." (Revelation 19:9-10)
The ones who are called to the marriage supper are blessed because they are the ones who have been redeemed by Christ's blood. The text gives no indication that this supper will be strictly for the New Testament Church. On the contrary, the evidence indicates that believers of all ages will be there. The text will soon disclose that the Bride consists of not only the Church but the saints of all time.
Overwhelmed by such visions, John foolishly falls down to worship the angel. Being an obedient servant of God, the angel quickly dispels any notion that such worship is acceptable. Only God is to be worshiped. This passage clearly forbids angel worship along with the adoration of anything or anyone but God (Exodus 20:3). One cannot judge John too harshly since such experiences would be sufficient to overwhelm any mortal man.
The Lord Jesus is the sole authority behind prophecy and teaching. If His Spirit is not present, the prophecy is not legitimate. In any portion of Scripture, Christ may be found either by direct reference, spirit or principle. Any teaching that does not magnify the Holy Spirit of Christ is a false teaching.
