The collect for today, the 4th Sunday after Trinity, from the 1662 Book of Common Prayer:

O God, the protector of all that trust in thee, without whom nothing is strong, nothing is holy; Increase and multiply upon us thy mercy; that, thou being our ruler and guide, we may so pass through things temporal, that we finally lose not the things eternal; Grant this, O heavenly Father, for Jesus Christ's sake our Lord. Amen.

The Epistle: Romans 8:18-23
The Gospel: St Luke 6:36-42
