On 24 November 1961, Pope John XXIII appointed Auxiliary Bishop Leo-Jozef Suenens as archbishop of the Archdiocese of Malines-Brussels, succeeding Cardinal Jozef-Ernest Van Roey.
Cardijn was still travelling in Latin America at this time and it is not clear when he learned of this appointment.
Unlike Van Roey, who had long supported Cardijn and the JOC, Suenens was not a supporter of the Specialised Catholic Action movements.
Indeed, in 1958, Suenens had published an article “L’unité multiforme de l’Action catholique” in which he criticised what he characterised as the “monopoly of Catholic Action” by “certain particular forms of organised lay apostolate” by which he meant the Specialised Catholic Action movements.
In addition, Cardijn had also experienced his own difficulties with Suenens, who as diocesan censor had sought to make the JOC chaplain change some of his writings.
Although we have no record of Cardijn’s reaction, the appointment must have concerned him.
