256. We note how much is required of us. The minister of the Lord should abstain from wine, so that he may be upheld by the good witness not only of the faithful but also by those who are without. For it is right that the witness to our acts and works should be the opinion of the public at large, that the office be not disgraced. Thus he who sees the minister of the altar adorned with suitable virtues may praise their Author, and reverence the Lord Who has such servants. The praise of the Lord sounds forth where there is a pure possession and an innocent rule at home.
