Unfortunately in our day many such bishops are unworthy of the office.
We have an incredible chapel of holy relics not far from here.

In our day? What was it St. John Chrysostom said about Hell being paved with bishop's skulls? No one is worthy of the episcopal office, though some, by God's grace, execute it well enough that in the end they will hear "Well done, good and faithful servant."
