Prosthesis has an interesting post in which he applies science based on movement to the pro-life understanding of what it means to be human. He concludes:
That is the crux of the pro-life position - this unity of movement and development in a human being. An embryo is not a different thing than an infant or a toddler or an adult. The pro-life position says that a human being has moral worth based on what he or she is and not on any characteristics that appear or disappear during his or her life. The latter is the very definition of discrimination - the unfair treatment of humans based on characteristics we have. We've slowly come to realize that discrimination based on gender, skin color, age and physical/mental handicap are wrong. The pro-life position is that discrimination based on size, degree of dependency on others, cognitive development, and other similar things are just as wrong.Please, read the entire post.
Beautiful. This is so related to Protestant difference as to salvation, too. They see it as a step we take, when we first correspond to God's grace. Catholics see it as a journey begun.
I am in awe of the so many ways that this world and God's revelation corresponds. I see the liturgical cycle in the earth's rotation (day & night), in the seasons, and the rotation around the sun. I see the Eucharist in Abraham's sacrifice of Isaac, in the Passover, and in the Jew's former daily sacrifice of two lambs.
I am so blessed to have been taught the Truth of Catholicism, and in God's grace that spurs me on to always learn more.
