He is bared of his lies and his secrets, stripped down to flesh and soul.
No priest today and only a single man makes up the congregation.
He sings modern hymns and keeps a sermon on life in his head as the holy water washes over him, cleansing him of his sins.
Then he takes the sacrement into his hands, and places it upon his head, and rinses it out in holy water... washing away the sins and wrongs and dirtiness of yesterday.
Then he steps out, born again or close enough, and wraps himself in linens like a newborn infant.
God is everywhere.
