Arguments drawn from the Old Testament types also pointed to the autumn as the time when the event represented by the “cleansing of the sanctuary” must take place. This was made very clear as attention was given to the manner in which the types relating to the first advent of Christ had been fulfilled. (GC 399.1) MC VC

The slaying of the Passover lamb was a shadow of the death of Christ. Says Paul: “Christ our Passover is sacrificed for us.” 1 Corinthians 5:7. The sheaf of first fruits, which at the time of the Passover was waved before the Lord, was typical of the resurrection of Christ. Paul says, in speaking of the resurrection of the Lord and of all His people: “Christ the first fruits; afterward they that are Christ’s at His coming.” 1 Corinthians 15:23. Like the wave sheaf, which was the first ripe grain gathered before the harvest, Christ is the first fruits of that immortal harvest of redeemed ones that at the future resurrection shall be gathered into the garner of God.

These types were fulfilled, not only as to the event, but as to the time. On the fourteenth day of the first Jewish month, the very day and month on which for fifteen long centuries the Passover lamb had been slain, Christ, having eaten the Passover with His disciples, instituted that feast which was to commemorate His own death as “the Lamb of God, which taketh away the sin of the world.”(Isaiah 53:10) That same night He was taken by wicked hands to be crucified and slain. And as the antitype of the wave sheaf our Lord was raised from the dead on the third day, “the first fruits of them that slept,” a sample of all the resurrected just(1 Chronicles 15:20), whose “vile body” shall be changed, and “fashioned like unto His glorious body.” Verse 20; Philippians 3:21.

In like manner the types which relate to the second advent must be fulfilled at the time pointed out in the symbolic service. Under the Mosaic system the cleansing of the sanctuary, or the great Day of Atonement, occurred on the tenth day of the seventh Jewish month (Leviticus 16:29-34), when the high priest, having made an atonement for all Israel, and thus removed their sins from the sanctuary, came forth and blessed the people. So it was believed that Christ, our great High Priest, would appear to purify the earth by the destruction of sin and sinners, and to bless His waiting people with immortality. The tenth day of the seventh month, the great Day of Atonement, the time of the cleansing of the sanctuary, which in the year 1844 fell upon the twenty-second of October, was regarded as the time of the Lord’s coming. This was in harmony with the proofs already presented that the 2300 days would terminate in the autumn, and the conclusion seemed irresistible. (GC 399.4) MC VC
