"We must understand what the warfare is. It is being fought not simply to enlarge the Church, but to bring souls into union with Christ. It is that strangest of wars which is fought for the enemy, not against him. Even the term 'enemy' must not be allowed to mislead.
Every unbeliever is, as every Catholic is, a being with an immortal spirit, made in the image of God, for whom Christ died. However violently hostile to the Church or to Christ he may be, our aim is to convert him, not simply to defeat him. We must never forget that the devil wants his soul in hell as he wants ours, and we must fight the devil for him. We may be forced to oppose a man to prevent his endangering souls; but always we want to win him for his own soul's salvation. It is in the power of the Holy Spirit (sic) that we must fight, and he is the Love of the Father and the Son; in so far as the Church's soldiers fight in hatred, they are fighting against him."
- F. J. Sheed: Theology for Beginners
We must recover the urgent concern for souls - for each individual, priceless soul - that the saints of old display.
