The bishops I'm familiar with live in rented houses, or apartments in the chancery office, or in rectories, or at the seminary, with two exceptions, and in both cases, their houses were given to them by rich laymen.
I don't care why Myers built his house; he was not out on the street, looking for a place to live.
Unseemly is closing a Catholic school while building yourself a big house. Likely entirely justified, but unseemly.
