"I am determined not to assume the sacerdotal office; for I have seen many men whom I have regarded as persons of good character and liberal dispositions, degenerate into avarice, sloth, and dissipation, in consequence of their introduction into the priesthood. — Fearing lest this should be the case with myself, I have resolved to spend the remaining term of my pilgrimage as a layman; for I have too frequently observed, that your brethren, at the time of their tonsure, not only part with their hair, but also with their conscience and their virtue."
