No, if a man (a priest) can determine who gets access to God and to when, he is not a minister, he's an administer...
God has no administers...He only has ministers...
There are necessary steps before a Catholic should even GO to Confession. One is the Act of Contrition, when the pentitent CONFESSES TO GOD his/her fault.
You recall the story of the ten lepers. Jesus Himself said, "Go, show yourself to the priest." Sin is a spiritual leprosy.
