A bishop holds the highest office of the church (there is no Patriarch or Pope over bishops).

But the Pope rarely criticizes individual governments and, like his predecessors, he does pose for pictures and bargain over bishops.

The two knights, then, can appear in any of the remaining five squares (skipping over bishops and queen) in 10 ways.

They will join Vatican-based cardinals who hold sway over doctrine, bishops and priests.

All princes should kiss his feet, and his legates took precedence over bishops.

Sometimes this carries jurisdiction over metropolitan bishops, but usually it is purely honorific.

The bishop of the provincial capital, the metropolitan, enjoyed certain rights over other bishops in the province, later called suffragans.

Each patriarch had jurisdiction over bishops in a specified geographic region.

St. Augustine, for example, argued against the supremacy of the bishop of Rome over other bishops.
