Veneration of the Prince began right at his burial, where a remarkable miracle took place. The saint extended his hand for the prayer of absolution (a written document placed in the coffin). Great Prince John (1353-1359), in his spiritual testament written in the year 1356, left to his son Demetrius (1363-1389), the future victor of the Battle of Kulikovo, “an icon of St Alexander.” The incorrupt relics of the holy Prince were uncovered, because of a vision, before the Battle of Kulikovo in the year 1380, and then they were sent forth for a local celebration.
Russian commanders asked for the intercession of the holy Prince, glorified by his defense of the Fatherland, in the following times: On August 30, 1721 Peter I, after a lengthy and exhausting war with the Swedes, concluded the Nishtad Peace. On this day it was decided to transfer the relics of the holy Prince Alexander Nevsky from Vladimir to the new northern capital, Peterburg, on the banks of the Neva. Removed from Vladimir on August 11, 1723, the holy relics were greeted at Shlisselburg on September 20 of that year and remained there until 1724. On August 30, they were placed in the Trinity Cathedral of the Alexander Nevsky Lavra, where they now rest in St Petersburg. By an edict on September 2, 1724 a feastday was established on August 30 (in 1727 the feast was discontinued because of secular matters, which involved clique struggles at the imperial court. In 1730 the Feast was again re-established).
Archimandrite Gabriel Buzhinsky (later Bishop of Ryazan, + April 27, 1731) compiled a special service in remembrance of the Nishtad Peace, combining with it a service to St Alexander Nevsky.
The name of the Defender of the borders of Russia and the Patron of Soldiers is famous far beyond the borders of Russia. The numerous temples dedicated to St Alexander Nevsky bear witness to this. The most famous of them: the Patriarchal Cathedral at Sofia, the Cathedral church in Talinin, and a church in Tbilisi. These churches are a pledge of friendship of the Russian National-Liberator with brother nations.
