The true peace of Christ
...the peace which [Jesus Christ] came to bring is not synonymous with the absence of conflicts. On the contrary, the peace of Jesus is the fruit of a constant struggle against evil. The fight which Jesus decided to wage is not against men or human powers, but against the enemy of God and man, Satan.
Whoever wishes to resist this enemy by remaining faithful to God and goodness must necessarily face incomprehensions, and, at times, true and actual persecutions. Therefore, those who intend to follow Jesus and devote themselves to truth without compromises must know that they will face oppositions and shall become, despite of themselves, a sign of division among others, even within their own families. Love for parents is in fact a holy commandment, but, for it to be lived in an authentic way, it may never be placed before the love of God and of Christ.
In such a way, on the steps of the Lord Jesus, Christians become "instruments of his peace", according to the famous expression of Saint Francis of Assisi. Not of an inconsistent and superficial peace, but of a real [peace], sought with courage and tenacity in the daily struggle to overcome evil by good [cf. Romans xii, 21] and paying in the flesh the price which this entails.
