Small Catechism for Memorizing - Trinity IV (June 15)

Confession: What do you believe according to these words (from John 20:22-23 concerning the Office of the Keys)?

I believe that when the called ministers of Christ deal with us by His divine command, in particular when they exclude openly unrepentant sinners from the Christian congregation and absolve those who repent of their sins and want to do better, this is just as valid and certain, even in heaven, as if Christ our dear Lord dealt with us Himself.
