CHESTER Bishop Kevin J. Sweeney joined newly ordained diocesan priests, seminarians, and young men, who are discerning their vocation, on Aug. 5 for a Mass and barbecue, sponsored by the diocesan Vocations Office and held at St. Lawrence the Martyr Church here. The event included evening prayer and Mass, a barbecue cooked and served by members of the Paterson Federation of the Knights of Columbus, and a game of soccer. At the Mass, the Bishop preached about his devotion to St. John Vianney, whose feast day the Church celebrated the day before.
