On 9 April 1963, a day after Cardijn had met with Suenens, the imprimatur was granted for his book.
Stefan Gigacz explains:
While there appears to be no written record of the meeting between the two men (Suenens and Cardijn), the outcome was swift. The next day, 9 April 1963, the vicar general, Msgr P. Theeuws, gave his imprimatur, accepting the modifications that Cardijn had made to his text.
Did Suenens blink? Fiévez and Meert certainly thought so, writing in their biography of Cardijn that he ‘stood firm’ despite the pressures that were placed on him ‘to change his emphasis.’ Moreover, while remaining rigidly faithful to his vow of obedience, Cardijn had forced Suenens to face up to his own responsibilities.
The whole episode left a bitter taste in the mouths of Fiévez and other close collaborators of Cardijn who were familiar with what had occurred.
Cardijn was deeply affected, even though he sought to avoid embarrassing Suenens, going as far as asking Fiévez to recover the initial proofs from the typesetter to ensure that these were not circulated.All things considered, Cardijn’s attitude demonstrated almost heroic forbearance.
