Saint John before the Latin Gate

Merciful Lord, we beseech thee to cast thy bright beams of light upon thy Church, that it being enlightened by the doctrine of thy blessed Apostle and Evangelist Saint John, may so walk in the light of thy truth, that it may at length attain to the light of everlasting life; through Jesus Christ our Lord. Amen.

¶ Or this:

Grant, we beseech thee, O merciful god, that, like thy holy Apostle and Evangelist Saint John, we may by thee be delivered unharmed from all the malice of the enemy: and also be made ready to receive from thee a revelation of that divine glory wherein though with thy Son and the Holy Spirit livest and reignest, world without end. Amen.
