It’s not opinion, we have his letters you can check for yourself. He ridiculed the Christian interpretation of God. His vision of God had no trinity, never communicated with humans, never performed miracles, never influenced the world in any way after creating it. That’s why he used the word Creator not God. This vision of God was fashionable among the elites of the Enlightenment.
There are 56 signatories confirming the content of the Declaration of Indepence written as such for the citizens of the United States of America. It would therefore behoove us to interpret said document through the eyes of Thomas Jefferson and those of like mind only (and who most likely did not represent the religious norms of their day). That being said, Jefferson did acknowledge God to whom he owed his existence to.
Believe me, dear Sir: there is not in the British empire a man who more cordially loves a union with Great Britain than I do. But,
by the God that made me, I will cease to exist before I yield to a connection on such terms as the British Parliament propose; and in this, I think I speak the sentiments of America.
—Thomas Jefferson, November 29, 1775[5]
As such, the God to whom he refers to as the Creator in the Declaration is that entity which has created all men equal with inalienable rights the first of which is life .
Apparently the signers of the document didn’t think so. Abortion before the quickening was permitted under English Common Law. The signers of the Declaration had a perfect chance to outlaw abortion when they wrote the Constitution. They didn’t.
This however was based on a false understanding of when life began. By 1837 however all abortions were considered a felony. The CC by the way consistently believed that life began at conception (it’s those “darned” Protestants that are to be blamed

).
Nevertheless quickening was wrong and this is why: a woman feels the first movements of her baby in the 4 or 5th month:
"But pregnant women don’t “feel life” until four or five months!
The inside of the uterus has no feeling. The baby has to be almost a foot long (30 cm.) and weigh about one pound (454 gm.) before he or she is large enough to brace a shoulder against one wall and kick hard enough against the opposite wall to dent it outward. Then the mother feels it because the outside of the uterus is covered by a sensitive peritoneal surface."
In actuality a human fetus begins to move:
“In the sixth to seventh weeks. . . . If the area of the lips is gently stroked, the child responds by bending the upper body to one side and making a quick backward motion with his arms. This is called a ‘total pattern response’ because it involves most of the body, rather than a local part.” L. B. Arey, Developmental Anatomy (6th ed.), Philadelphia: W. B. Sanders Co., 1954
At eight weeks, “if we tickle the baby’s nose, he will flex his head backwards away from the stimulus.” A. Hellgers, M.D., “Fetal Development, 31,” Theological Studies, vol. 3, no. 7, 1970, p. 26
Another example is from a surgical technician whose letter said, "When we opened her abdomen (for a tubal pregnancy), the tube had expelled an inch-long fetus, about 4-6 weeks old. It was still alive in the sack. “That tiny baby was waving its little arms and kicking its little legs and even turned its whole body over.” J. Dobson, Focus on the Family Mag., Aug. ’91, pg. 16
Look at it this way… Wouldn’t you like the whole world to come to the RCC? But do you expect it in your lifetime? I’m not looking for middle ground, but a better understanding of people sharing the planet.
