“Faith and Reason are like two wings of the human spirit by which is soars to the truth.”

“Faith and reason are like two wings on which the human spirit rises to the contemplation of truth; and God has placed in the human heart a desire to know the truth- in a word, to know himself- so that, by knowing and loving God, men and women may also come to the fullness of truth about themselves.”

“Yesterday was a dark day in the history of humanity, a terrible affront to human dignity. After receiving the news, I followed with intense concern the developing situation, with heartfelt prayers to the Lord. How is it possible to commit acts of such savage cruelty? The human heart has depths from which schemes of unheard-of ferocity sometimes emerge, capable of destroying in a moment the normal daily life of a people. But faith comes to our aid at these times when words seem to fail. Christ’s word is the only one that can give a response to the questions which trouble our spirit. Even if the forces of darkness appear to prevail, those who believe in God know that evil and death do not have the final say. Christian hope is based on this truth; at this time our prayerful trust draws strength from it. ~General Audience, September 12, 2001.”

“Truth can prevail only in virtue of truth itself.”

“Original sin is not only the violation of a positive command … but … attempts … to abolish fatherhood, destroying its rays which permeate the created world, placing in doubt the truth about God who is Love and leaving man with only a sense of the master-slave relationship.”

“Humankind, which discovers its capacity to transform and in a certain sense create the world through its own work, forgets that this is always based on God's prior and original gift of things that are. People think that they can make arbitrary use of the earth, subjecting it without restraint to their wills, as though the earth did not have its own requisites and a prior God-given purpose, which human beings can indeed develop but must not betray.”

“The earth will not continue to offer its harvest, except with faithful stewardship. We cannot say we love the land and then take steps to destroy it for use by future generations.”
