On 31 January 1963, Mgr Jean Streiff, the secretary for Catholic Action in France, wrote to Mgr Achille Glorieux informing him that Cardinal Liénart had forwarded him a letter appointing him as a peritus for the Lay Apostolate Commission.
Paris, 31 January, 1963
Vatican City – ROME
His Eminence Cardinal LIENART, back from Rome, sends me a letter of appointment and a card of “Peritus” from the Council.
He asks me in his letter to place me at your disposal immediately, which I gladly do.
In a few days we have a meeting of the National Committee for the Apostolate of the Laity and we have included in the program the remote preparation of the World Congress and the search for the best method to work usefully and efficiently on the texts that you kindly sent us.
Be assured, dear Monsignor, of the assurance of my prayers for your work which affects us so closely in the expression of my religious and very friendly sentiments.
Monsignor Jean STREIFF
Secretary General of Catholic Action
