-- Acts 9:1-20
In her Magisterial teaching of the faith and in the witness of her saints, the Church has never forgotten that "sinners were the authors and the ministers of all the sufferings that the divine Redeemer endured." Taking into account the fact that our sins affect Christ himself, the Church does not hesitate to impute to Christians the gravest responsibility for the torments inflicted upon Jesus, a responsibility with which they have all too often burdened the Jews alone:
We must regard as guilty all those who continue to relapse into their sins. Since our sins made the Lord Christ suffer the torment of the cross, those who plunge themselves into disorders and crimes crucify the Son of God anew in their hearts (for he is in them) and hold him up to contempt. And it can be seen that our crime in this case is greater in us than in the Jews. As for them, according to the witness of the Apostle, "None of the rulers of this age understood this; for if they had, they would not have crucified the Lord of glory." We, however, profess to know him. And when we deny him by our deeds, we in some way seem to lay violent hands on him. (Roman Catechism)
Nor did demons crucify him; it is you who have crucified him and crucify him still, when you delight in your vices and sins. (St Francis of Assisi)
