The Church is Pro-God, Pro-Reality, and Pro-Life.
The Church believes in God, in truth, in reality–“We believe in one God . . . maker of heaven and earth, and of all things visible and invisible”–the Church believes in God and creation. And this belief is the foundation for a Pro-Life ethic. Social Justice for the unborn (life-in-the-womb) must be rooted in this grammar–God is the sovereign creator of heaven and earth, of that which is seen and unseen, and He alone creates and defines this (all) reality.
That being the case, what does the Creator say about in utero? Is He silent about the reality of the life of cells multiplying in a womb? Hardly–See Exodus 21, Psalm 22, 139.
