Feast days after the cross

For Seventh-day Adventists, a leading theologian's conclusion about the feast days:

A fourth surprise was to discover that I was wrong in assuming that the annual Feasts came to an end with the sacrifice of Christ, simply because they were connected with the sacrificial system of the Temple. I came to realize that the continuity or discontinuity of the Feasts is determined not by their connection with the sacrificial system, but by the scope of their typology. If the Feasts had typified only the redemptive accomplishments of Christ's first Advent, then obviously their function would have terminated at the Cross. But, if the Feasts foreshadow also the consummation of redemption to be accomplished by Christ at His second Advent, then their function continues in the Christian church, though with a new meaning and manner of observance.
