The inspiration of Pope Pius XII
All recognize in Pius XII an intelligence out of the ordinary, a memory of iron, a singular aptitude for foreign languages, and a notable sensibility. It has been said that he was an accomplished diplomat, an eminent jurist, a great theologian. This is all true, but it does not explain it all. There was also within him a continuous effort and a firm will to give himself to God, selflessly and with no concern for his own poor health.
The true motivation for his behavior was this: all originated out of love for his Lord Jesus Christ, an out of love for the Church and for mankind. He was in fact, above all, the priest in constant and intimate union with God, the priest who found the strength for his incalculable labor in long periods of prayer before the Most Holy Sacrament, in silent conversation with his Creator and Redeemer. Whence his Magisterium, as well as all his other activities, derive their source and impulse.
