Thanks to Cincinnatus for bringing into focus for me a great paradox: On the day after we mark the breaking of the church due to the always necessary struggle against how the church tends to fall into corruption and the obscuring of Christ’s Gospel (Reformation Day), we celebrate the unity of the church, how all who have faith in Christ constitute the everlasting “communion of the saints” (All Saints’ Day).
And now on that holiday, we can turn to the Lutheran Confessions to see how saints ought to be honored:
Our Confession approves honoring the saints in three ways. The first is thanksgiving. We should thank God because He has shown examples of mercy, because He wishes to save people, and because He has given teachers and other gifts to the Church. These gifts, since they are the greatest, should be amplified. The saints themselves, who have faithfully used these gifts, should be praised just as Christ praises faithful businessmen (Matthew 25:21, 23). The second service is the strengthening of our faith.When we see Peter’s denial forgiven, we also are encouraged to believe all the more that grace truly superabounds over sin (Romans 5:20). The third honor is the imitation, first of faith, then of the other virtues. Everyone should imitate the saints according to his calling. The adversaries do not require these true honors. They argue only about invocation, which, even if it were not dangerous, still is not necessary.
