Next, John convened the Synod of Westminster in September 1125, which was attended by both the archbishops of Canterbury and York, together with twenty bishops and forty abbots. Although the synod issued rulings on the forbidding of simony and of holding multiple sees at the same time, it did not touch on the vexed question of primacy between Canterbury and York. Instead, John summoned the two prelates to travel with him to Rome to discuss the matter in person before Honorius. They arrived in late 1125 and were greeted warmly by Honorius, and they remained in Rome until early 1126. While there, Honorius ruled that the Bishop of St Andrews was to be subject to the Archbishop of York and in the more contentious issue, he attempted to circumvent his way around the problem by declaring that Thurstan was subject to William de Corbeil, not in his role as Archbishop of Canterbury, but as papal legate for England and Scotland. To emphasise this, Honorius decreed that the Archbishop of Canterbury could not ask for any oath of obedience from the Archbishop of York, and in the matter of honorary distinction, it was the Archbishop of Canterbury in his role as Legate that was the most elevated ecclesiastic in the kingdom.
