However, I did not know this until just now and it was published by Lifesite news. This is what Pope Francis said to the United Nations yesterday:
Pope Francis calls on UN to uphold right to life and the natural family“The defense of the environment and the fight against exclusion demand that we recognize a moral law written into human nature itself, one which includes the natural difference between man and woman, and absolute respect for life in all its stages and dimensions."
“The common home of all men and women must continue to rise on the foundations of a right understanding of universal fraternity and respect for the sacredness of every human life,” he said, “of every man and every woman, the poor, the elderly, children, the infirm, the unborn, the unemployed, the abandoned, those considered disposable because they are only considered as part of a statistic.”
My comments: I challenge all of you to read the second chapter of Laudato Si. In this chapter the Holy Father gives a brilliant explanation of Creation prior to the fall, what Original and Actual sin are and do to our relationship with God, each other and the environment, and the intrinsic value of natural law.
Natural Law and observing it is at the core of the pope's teaching on the environment which ties into every other moral teaching of the Church. Natural Law, though, it available to all even those who reject Scripture and Tradition. In the new evangelization, an appeal to Natural Law rather than Sacred Scripture and Tradition would seem to be obvious especially when dealing with non-believers as the Holy Father was doing both in Congress and especially in the United Nations.
