Collect

Merciful Lord,
cast your bright beams of light upon the Church:
that, being enlightened by the teaching
of your blessed apostle and evangelist Saint John,
we may so walk in the light of your truth
that we may at last attain to the light of everlasting life;
through Jesus Christ your incarnate Son our Lord,
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.

Post Communion

Grant, O Lord, we pray,
that the Word made flesh
proclaimed by your apostle John
may, by the celebration of these holy mysteries,
ever abide and live within us;
through Jesus Christ our Lord.

BCP Collect

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.
