“O woe! You are in the Divine Liturgy, and while the Royal Table is prepared, while the Lamb of God is sacrificed for your sake, while the priest is struggling for your salvation, you are indifferent. At the time when the six-winged Seraphim cover their faces from awe and all the heavenly powers together with the priest beseech God for you, at the moment the fire of the Holy Spirit descends from Heaven and the blood of Christ is shed from His immaculate side in the holy Chalice, at this moment, I wonder, doesn’t your conscience censure you for your lack of attention? “
(St John Chrysostom, ‘On Church Attendance’)
