It would be right to describe the publication of Amoris Laetitia by Pope Francis as a minor earthquake, though one preceded by plenty of warning tremors. And while the Catholic Church’s foundations may have been shaken, the walls and roof are still standing. Francis was well aware when he was elected Pope that the basic weakness in the Church’s mission to evangelise was its reputation as a stern and unforgiving teacher in the field of sexual and marital ethics, something that touches people’s lives most intimately. Put simply, it did not sound like the gentle voice of a loving mother. Francis had to respect as far as possible the content of the teaching. But he could change the one thing that may matter more than content for ordinary Catholics – its tone.
