This week’s prayer is from the Liturgy of St. Mark (2nd century):

O Soverign and almighty Lord, bless all thy people, and all thy flock. Give thy peace, thy help, thy love unto us thy servants, the sheep of thy fold, that we may be united in the bond of peace and love, one body and one spirit, in one hope of our calling, in thy divine and boundless love.
