This is from the fourth Sunday after Trinity, which was yesterday (the reading is Luke 6, for those interested).
The collect: 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.
Be ye therefore merciful, as your Father is also merciful. Judge not, and ye shall not be judged; condemn not, and ye shall not be condemned; forgive, and ye shall be forgiven; give and it shall be given unto you, good measure, pressed down and shaken together, and running over shall men give into your bosom.
Look out for some previews of book IV in the next few days. It might just start to make sense then...
When to the sessions of sweet silent thought
