Yesterday was Pentecost, the birthday of the Catholic Church. It is good to remember how the Apostles began their ministry. The first Gospel had not even been written.
"For 1,400 years the world was left without a Bible -- not one in ten thousand, not one in twenty thousand, before the art of printing was invented, had the Bible. And would our Divine Lord have left the world without that book if it was necessary to man's salvation? Most assuredly not."--"The Church or the Bible" by Fr. Arnold Damen.
