That is, if each person is free to engage in use of any and all reproductive technology available for producing a child, such as through the making of embryos in a laboratory and the implantation of those embryos in any woman, married or not, then marriage no longer has anything to do with human reproduction. The biological then becomes separated from the relational and marriage no longer has the meaning intended by God. It is possible, in a fallen world, to think of ourselves as being in charge of human life, of bringing children into existence by our own will when and how we please. However, producing children artificially in a laboratory as a woman's right, or to satisfy a researcher's moribund scientific curiosity, or to comply with what may become a desperate couple's demand, defiles a relationship with God and distorts the meaning of children as a gift from God to be given only in the fullness of time. The Gospel message in marriage is that God has revealed something of his own plan of salvation in marriage.
Marriage is more than it appears.
As in the loving embrace on the cross God gives us the new birth of eternal life, so in the loving embrace of marriage a child is given life. These replies to someone who rejects the idea of morality are responses based on reason rather than revelation. I recently had the opportunity to hear a presentation by a well-known prolife speaker on abortion. In meticulous fashion he presented his case which in substance said that if you can prove to an abortion proponent or a woman considering abortion that the fetus is a human being you have won your argument. Winning means that the proponent will give up his case or a woman considering abortion will not submit to an abortion.
