Deus, qui infirmitáti nostræ ad teréndam salútis viam in Sanctis tuis exémplum et præsídium collocásti: da nobis, ita beáti Guliélmi Abbátis mérita venerári; ut ejúsdem excipiámus suffrágia et vestígia prosequámur.
O God, Who made Your Saints an example and a help for our weakness; grant us, as we walk the path of salvation, so to venerate the virtues of the blessed Abbot William that we may obtain his intercession and follow in his footsteps.
