The Fast of the Holy Apostles begins on Monday, June 4 (May 22 o.s.) and extends until the day before the Feast of the Holy Apostles Peter and Paul on July 12 (June 29 o.s.). This, the first fast of the Summer months, helps us as we struggle to work out our salvation and to follow in the footsteps of the Holy Apostles as they spread the gospel of the Risen Christ to every corner of the world. This fast is not as strict as the Lenten and Dormition Fasts, so check your calendars to know when there is katalysis (relaxation) of the fasting guidelines to allow for wine and oil or even fish.

Lord! How characteristic it is of human beings to attract and assimilate images, to settle into them and reside in them—whilst for them, as being made in Thine image, it should be natural to strive with all love and zeal towards the First Image, and cleave to Him. But this greedy, pleasure-loving, flabby, and sluggish flesh of ours pulls us away from Thee. We need fasting and temperance, but we are passionate for pleasures. Strengthen us for abstinence!
