By St. Symeon of Thessaloniki
The fast in August was established in honor of the Mother of God the Word; who, foreknowing her repose, ascetically labored and fasted for us as always, although she was holy and immaculate, and had no need for fasting. Thus, she especially prayed for us in preparation for being transported from this life to the future life, when her blessed soul would be united through the Divine Spirit with her Son. Therefore, we also should fast and praise her, emulating her life, urging her thereby to pray for us. Some, by the way, say that this fast was instituted on the occasion of two feasts — the Transfiguration and the Dormition. I also consider it necessary to remember these two feasts — one which gives us light, and the other which is merciful to us and intercedes for us.
