You should speak to the confessor thus: Reverend and dear sir, I beseech you to hear my confession, and to pronounce forgiveness to me for God's sake.
I, a poor sinner, confess myself before God guilty of all sins; especially I confess
(insert sins here)
Then shall the confessor say:
God be merciful to thee and strengthen thy faith! Amen.
Dost thou believe that my forgiveness is God's forgiveness?
Yes, dear sir.
Then let him say:
As thou believest, so be it done unto thee. And by the command of our Lord Jesus Christ I forgive thee thy sins, in the name of the Father and of the Son and of the Holy Ghost. Amen. Depart in peace.
But those who have great burdens upon their consciences, or are distressed and tempted, the confessor will know how to comfort and to encourage to faith with more passages of Scripture. This is to be merely a general form of confession for the unlearned.
