 Bricius was one of the most important clerics in the Scotland of his time, that is, during the later part of the reign of William the Lion (r. 1165–1214) and early part of the reign of Alexander II (1214–1249).For instance, in 1207, Pope Innocent III appointed him judge-delegate of a dispute between Melrose Abbey and the Earl of Dunbar, two of the most important landowners in what for Moray-based Bricius was the remote English-speaking south-east of Scotland.In 1215, Bricius was one of three Scottish bishops to attend the Fourth Lateran Council at Rome (the other two were William de Malveisin, bishop of St Andrews and Walter, bishop of Glasgow).
