That's a really facile interpretation of the situation. There is mercy available for everyone - as St Isaac the Syrian says, "As a handful of sand in the boundless ocean, so are the sins of all flesh in comparison with God's providence and mercy. As a copious spring could not be stopped up with a handful of dust, so the Creator's compassion cannot be conquered by the wickedness of creatures." No one is denying second chances, improvement, becoming holy. That is part and parcel to being a Christian. The Church is full of sinners, its a hospital for the sick, that's why we go.
At the same time, being a priest or a clergyman has requirements over and above that. The Church has held this since the beginning - way back in Nicaea in 325 AD the principle was established that for the priesthood "the Church requires that which is blameless." St Basil the Great writes "On the matter of priesthood, if you fell into a sin of the flesh...even if you didn't know that these sins are impediments to the priesthood, you are not allowed to become a priest … examine yourself well, and if you fell even once even out of ignorance you cannot become a priest. No matter how great a need the Church has. God will care for His Church...If you have an impediment to the priesthood, you are able by repentance and confession to perform miracles and to become a saint, but not a priest."
There are, and should be, higher standards for being a clergyman than being a layperson. For example, the Apostolic Canons (c 400) say "If a bishop, presbyter, or deacon is caught in fornication, perjury, or theft, let him be deposed."
St Cyril of Alexandria (c 442) wrote "if [a bishop is] unworthy, do not let them leave by retiring, rather let them be judged for [their] actions." In other words, a bishop who should be deposed does not have the option of simply retiring to avoid it. It certainly is not acceptable for a clergyman who has some kind of scandal worthy of being deposed to move churches and continue to act in a pastoral capacity. As St Basil says, they can become saints, but they should no longer be pastors.
Edit to add - I am speaking in generalities. I know nothing about this particular matter, and am not commenting on it at all.
