St John, Apostle and Evangelist

MERCIFUL Lord, we beseech thee to cast thy bright beams of light upon thy Church, that it, being illumined 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 life everlasting; through Jesus Christ our Lord. Amen.

The Season is Christmastide, within the Octave of Christmas, the Liturgical Color is White.
