Von Speyr: On Scandal

John 13:11 For he knew who was to betray him. That is why he said: You are not all clean.

The Lord knows his betrayer, but he does not point him out, for outwardly he still belongs to the community, although inwardly he has turned away from the Lord. The Lord does not expel anyone; a person who goes away has excluded himself. Before the community, the Lord does not give a hint as to who will leave it soon, for the scandal is not yet public. So, too, the Church will not bring scandals to light before the instigators themselves give occasion for it. 

The scandal of Judas was one that had to happen, but many another scandal in the Church has no visible cause. Yet the Lord does not spare her such scandal. Is it because the Lord himself took upon himself the scandal of the Cross? Is it because through one person's scandal the other members of the Chruch are horrified and thus strengthened in their loyalty to the Church? In any case, the offense is tolerated, even if it affects the Church's holy of holies. The Lord endures it in the room at the Last Supper. The Church must endure scandal; she may not circumvent or deny it, or act as if it were not there, or distance herself from it. Nor is it said that the Church should immediately and by all means stifle the scandal by eliminating the evil, for perhaps the sinner may still repent. Nor does the Lord cast Judas out - it can be better to let an abscess ripen than to put a knife to it too soon and kill it in its early stages. Not every scandal rousing book needs to be immediately banned, even if it may not keep the Church's doctrine intact. Perhaps it is better to talk first and to clear up misunderstanding by the light of day, and fairly. Many in the Church are sinners. and every sin is a tacit scandal and a heresy. But the Church is held together by love.
