Proverbs.
It is done secundum usum Sarum.]
This Proverb coming out of the Church, hath since inlarged it self into a civil use. It began on this occasion; Many Offices or forms of service were used in severall Chur∣ches in England, as the Office of York, Hereford, Bangor, &c. which caused a deal of Confusion in Gods Worship, untill Osmond Bishop of Sarum, about the year of our Lord 1090. made that Ordinall or Office which was generally received all over Eng∣land, so that Churches thence forward easily understood one another, all speaking the same words in their Liturgy.
It is now applyed to those persons which do, and Actions which are formally and so∣lemnly done, in so Regular a way by Authentick Precedents, and Paterns of unquestionable Authority, that no just exception can be taken thereat.
