As we enter the Church for the Divine Liturgy, where we are to "leave aside every earthly care" and "With fear of God and faith and love, draw near" to receive the Body and Blood of Christ, we are reminded by the great Archangels Michael and Gabriel of the awesome "work of the people," (liturgy or leitourgia) into which we are about to enter.
As we leave the Cloud of Witnesses Chapel to go into the world in our daily lives, we are emboldened by the Martyrs Sts. George and Demetrius who fought evil and triumphed in their martyrdom.
