A day after meeting with the JOC, ACO and the FIMOC, Cardijn wrote on 27 September 1960 to Mgr Achille Glorieux, who had been appointed secretary to the new PCLA.
“We met in Paris yesterday with the leaders of the ACO, FIMOC and JOC Internationale to examine the possibility of international collaboration. We also considered how each movement itself and all together we could do useful work by sending to the Lay Apostolate Commission and even to other commissions one or more documents proposing a study of certain issues and experiences of solution in the field of the worker apostolate, both young and adult.
“During our discussions, we even asked if we could not propose the creation of a sub-commission comprising lay leaders and militants to submit to the Pontifical Commission their point of view, experiences as well as the wishes of the lay apostles themselves with respect to the apostolate to which they had devoted their whole lives.
“This sub-commission could work at international level or diversify into continental sub-commissions, which would examine the issue from an even more realistic perspective on a continent by continent basis.
“The issue of the worker apostolate seems to me to be so important within the ensemble of issues of the lay apostolate that I do not hesitate to ask you if it would be opportune to make such a proposal.
“If you could consult His Eminence Cardinal Cento on this subject, you could then suggest to use the right attitude to take. I am ready myself to come and speak with His Eminence if he judges it opportune.
“This collaboration of the laity themselves in the preparation of the coming Ecumenical Council seems highly opportune to me at the moment when the World Council of Churches in Geneva is preparing its own World Congress in New Delhi next year on the theme “Christ, Light of the World” and has issued an enthusiastic call to the faithful of all faiths, as well as at a time when Moral Rearmament has redoubled its activity in Africa with all African parties as well moreover will all people of colour,” Cardijn wrote.
