Pope Francis has said the family is under attack from 'worldly centers of power'.
The survival of the family is compromised by 'worldly' powers but the homicide was carried out by disordered priests who taught (and continue to presently teach) disordered catechesis - or do not teach at all.
The enemy within.
As for the new things which we can find in this [Fatima] message today, there is also the fact that attacks on the Pope and the Church come not only from without, but the sufferings of the Church come precisely from within the Church, from the sin existing within the Church. This too is something that we have always known, but today we are seeing it in a really terrifying way: that the greatest persecution of the Church comes not from her enemies without, but arises from sin within the Church, and that the Church thus has a deep need to relearn penance, to accept purification, to learn forgiveness on the one hand, but also the need for justice. Pope Benedict XVI
