Young Christian Workers
In the 1960s, at the height of the dispute between the Maltese Church and the Labour Party, Mifsud Bonnici was an official of a number of lay organisations connected to the Church, including the Catholic Social Guild and the Young Christian Workers Movement (also as editorial board member of their "Il-Haddiem" newspaper), and supported the "diocesan junta" of Church organisations opposing Dom Mintoff and his Party. He would later claim to be "a Nationalist by birth, but a Labourite through free choice and conviction".
