From St Faustina’s Diary:
Today, the Lord has been teaching me, once again, how I am to approach the Sacrament of Penance:
My daughter, just as you prepare in My presence, so also you make your confession before Me.
The person of the priest is, for Me, only a screen.
Never analyze what sort of a priest it is that I am making use of; open your soul in confession as you would to Me, and I will fill it with My light.
