Today is the feast of St Matthias, the Apostle chosen to replace Judas Iscariot. The first reading at Mass speaks of his appointment; St Peter says that Judas must be replaced, quoting the words of Psalm 108 (109): "Let someone else take his office". From that day, the office of the Apostles has been renewed by the appointment of successors: the bishops of the Church. The large number of bishops who attended the recent episcopal ordination reminded us of their duty to pass on their duties and their authority, for the good of the Church. To mark the day, and in the light of Bishop Campbell's recent ordination, below is a gallery of all the bishops who have served in Lancaster since the Diocese was founded in 1924.
