St. Augustine writing to St. Jerome mentions wealthy candidates for church offices being favored over poor candidate with better credentials:
Nor, indeed, in my opinion, are we to esteem it a trifling sin “to have the faith of our Lord Jesus Christ with respect of persons,” if we take the difference between sitting and standing, of which mention is made in the context, to refer to ecclesiastical honours; for who can bear to see a rich man chosen to a place of honour in the Church, while a poor man, of superior qualifications and of greater holiness, is despised?
Ramsay MacMullen says, “In eastern episcopal elections in the same decade or so, candidates were promoted (i.e. it was assumed they would be broadly favored) on the basis of their pedigree or money…or as fugitives from other, earlier fueds. MacMullen refers to St. John Chrysostom in his “On the Priesthood” 3.15 (here), who says:
Come, then, and take a peep at the public festivals when it is generally the custom for elections to be made to ecclesiastical dignities, and you will then see the priest assailed with accusations as numerous as the people whom he rules. For all who have the privilege of conferring the honor are then split into many parties; and one can never find the council of elders of one mind with each other, or about the man who has won the prelacy; but each stands apart from the others, one preferring this man, another that. Now the reason is that they do not all look to one thing, which ought to be the only object kept in view, the excellence of the character; but other qualifications are alleged as recommending to this honor; for instance, of one it is said, “let him be elected because he belongs to an illustrious family,” of another “because he is possessed of great wealth, and would not need to be supported out of the revenues of the Church,” of a third “because he has come over from the camp of the adversary;” one is eager to give the preference to a man who is on terms of intimacy with himself, another to the man who is related to him by birth, a third to the flatterer, but no one will look to the man who is really qualified, or make some test of his character.
