The Church has never changed its teaching on the sanctity of human life - it didn't make up a rule for the convenience of a particular time like a rule at a country club as the Governor would have us believe.
Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.
The universe is one great kindergarten for man. Everything that exists has brought with it its own peculiar lesson. The mountain teaches stability and grandeur; the ocean immensity and change. Forests, lakes, and rivers, clouds and winds, stars and flowers, stupendous glaciers and crystal snowflakes--every form of animate or inanimate existence, leaves its impress upon the soul of man.
