28 Moreover, he inculcated the maxims which we frequently find in his writings in such form as this: "In what frame of mind does one enter upon the office of mediator between God and man who is not conscious of being familiar with grace through a meritorious life?" ( Reg. Past .i. 10). "U passion lives in his actions, with what presumption does he hasten to cure the wound, when he wears a scar on his very face?" ( Reg. Past . i. 9). What fruit can be expected for the salvation of souls if the apostles "combat in their lives what they preach in their words?" ( Reg. Past. i. 2). "Truly he cannot remove the delinquencies of others who is himself ravaged by the same" ( Reg. Past . i. 11).
