In His unfathomable love for us, God reveals the mystery that He Himself is Love.
In the words of a great Father of the Church: "Anyone can grant favors, anyone can bestow gifts, any prosperous benefactor can love those who are deferential to him; but will he be comparable to Him who took the adversities of His own people onto Himself; who puts Himself forward to block dangers threatening His own; who hands Himself over to punishments for His own, who confronts death face-to-face in order to remove them from destruction and preserve them for life? Love is proved by adversities, the weight of affection is determined by the dangers endured, perfect charity is confirmed by death.... That dominion is true which commands by love, not by fear; which subjects both bodies and hearts to itself by means of affection; which by loving furnishes servants for itself who are not unwilling, but willing. [Jesus died because] He wanted it to be known how much God loved humanity, since He wanted to be loved rather than feared" (Saint Peter "Chrysologus" Archbishop of Ravenna [Fifth Century], feast day July 30th).
