Jesus said... But I, when I am lifted up from the earth,
will draw all men to Myself. ~ John 12:32
From a letter of Bl Niels Stensen (Danish) written prior to his conversion to Catholicism from Lutheranism, describing a Corpus Christi procession he witnessed in Leghorn, Italy, on June 24, 1666:
“When I saw the host carried amid such pomp across the city, the thought came into my mind: either this Host is a simple piece of bread and those who render it such are mad, or else It is truly the Body of Christ. In that case, why should I too not honor It? When this idea flashed across my mind… I could not persuade myself that so great a part of the Christian world was mad - - thinking of the Roman Catholics, among whom there were so many intelligent and learned men …
… I spent much time in seeking the truth, trusting to God to open my soul to the knowledge I sought in all sincerity of heart.”
