Thomas Aquinas,
Summa Theologiae — Question 185 - OF THINGS PERTAINING TO THE EPISCOPAL STATE…
“ On the other hand, he who enters the episcopal state is raised up in order to watch over others, and no man should seek to be raised thus, according to Heb. 5:4, "Neither doth any man take the honor to himself, but he that is called by God": and Chrysostom says: "To desire supremacy in the Church is neither just nor useful. For what wise man seeks of his own accord to submit to such servitude and peril, as to have to render an account of the whole Church? None save him who fears not God's judgment, and makes a secular abuse of his ecclesiastical authority, by turning it to secular uses." ”
