The central theme of the Three Ecumenical Symbols is Christ's person and work, the paramount importance of which Luther extols as follows in his tract of 1538: "In all the histories of the entire Christendom I have found and experienced that all who had and held the chief article concerning Jesus Christ correctly remained safe and sound in the true Christian faith. And even though they erred and sinned in other points, they nevertheless were finally preserved." "For it has been decreed, says Paul, Col. 2, 9, that in Christ should dwell all the fulness of the Godhead bodily, or personally, so that he who does not find or receive God in Christ shall never have nor find Him anywhere outside of Christ, even though he ascend above heaven, descend below hell, or go beyond the world." "On the other hand, I have also observed that all errors, heresies, idolatries, offenses, abuses, and ungodliness within the Church originally resulted from the fact that this article of faith concerning Jesus Christ was despised or lost. And viewed clearly and rightly, all heresies militate against the precious article of Jesus Christ, as Simeon says concerning Him, Luke 2, 34, that He is set for the falling and the rising of many in Israel and for a sign which is spoken against; and long before this, Isaiah, chapter 8, 14, spoke of Him as 'a stone of stumbling and a rock of offense.'" "And we in the Papacy, the last and greatest of saints, what have we done? We have confessed that He [Christ] is God and man; but that He is our Savior, who died and rose for us, etc., this we have denied and persecuted with might and main" (those who taught this). "And even now those who claim to be the best Christians and boast that they are the Holy Church, who burn the others and wade in innocent blood, regard as the best doctrine [that which teaches] that we obtain grace and salvation through our own works. Christ is to be accorded no other honor with regard to our salvation than that He made the beginning, while we are the heroes who complete it with our merit."
