On 18 February 1963, Brazilian bishop, Dom Eugenio Araujo Sales, also a member of the Lay Apostolate Commission, wrote to Cardijn approving the draft manuscript of his book, emphasising its timeliness.
My dear Monsignor Cardijn.
I received your letter of January 15, 1963, as well as your publication, which I am now reading carefully. I’m very interested. The position is very clear and I fully agree with your points of view. I believe,
Your Excellency, that we are at a moment of the utmost importance in determining the role of the laity in the Church. In the present apostolic situation, the participation of the well-trained layman will succeed in keeping the various de-Christianized or almost de-Christianized circles in the Church, or in bringing them back into it.
In prayer to God to bless your extraordinary work, I send you an affectionate blessing.
