One thing that must be dealt with is the Marriage Supper of the Lamb. Revelation 19:7–9 describes Christians in Heaven engaged in the Marriage Supper of the Lamb. Immediately after that event is described, Revelation 19:11 reveals the Lord riding out of Heaven with His saints at the end of the Tribulation to destroy His enemies. if Revelation 19:7 describes the Church being in Heaven before the end of the Tribulation, how did it get there? Well, it must have been raptured. Of course, if the Church is on earth throughout the whole Tribulation period, then when was it raptured to allow enough time for the Church to be caught up into Heaven, attend the Marriage Supper of the Lamb, and then return with Christ at His Second Advent?
The sequencing seems to be very clear. The Second Advent occurs at the end of the Tribulation; the Marriage Supper occurs before that; and then, before the Marriage Supper occurs, the Judgment Seat of Christ occurs so that the Church gets her rewards which she is seen wearing at the Marriage Supper of the Lamb.
As Revelation 3:10 says, “Because you have kept the word of my perseverance, I also will keep you from the hour of testing, that hour which is about to come upon the whole world, to test those who dwell upon the earth.” Believers will not only be kept from the testing, but the whole time period of the testing. How? 1 Thessalonians 4 says believers will be “caught up,” “snatched,” or “raptured,” from the earth to meet Christ in the clouds. That is why we “wait for God’s Son from heaven whom He raised from the dead, that is, Jesus, who delivers us from the wrath to come” (1 Thess. 1:10).
Or, as the Catholic Church has taught and believed from the beginning, the Marriage Feast of the Lamb occurred in time with Christ on the Cross. He is at once Priest, sacrificial offering and Bridegroom. We are joined with His once-for all sacrifice when we participate in His offering of the Last Supper--the Holy Mass. It is a timeless joining in this one-time Earthly event played out in all its Glory in Heaven as John saw the Lamb appearing as though slain. In this sharing, Heaven and Earth are joined and the Whole Church (Saints and Angels included) rejoice and sing the Holy, Holy, Holy together. As we believe in the Communion of Saints, we should recognize that this communion is not some future event but present in the here and now.
God bless you.
