When we examine Mary's situation from our own cultural perspective, we realize that she had every reason not to be open to life. She was barely a teenager, very poor and unmarried. If you consider the world she lived in, these reasons could constitute even more graveness than they would today. There was no Medicaid, no crisis pregnancy centers or shelters, and adultery could be punished by death. Despite this however, Mary said YES to life. It is through her YES, her fiat, that Jesus our salvation, came into the world. Moreover, it might be also be fair to point out that God only asked Mary to be receptive to a child once in her life. God's will for the Holy Family was to always remain a home of three. This is also a reminder for us as Catholics, that a marriage that is open-to-life will not always fill a twelve-passenger van.
There are many wonderful Church documents such as Humanae Vitae and the Catechism of the Church that can help us understand the Church's teaching on Christian marriages. Ultimately, husbands and wives must always pray to follow Mary's example of "thy will be done". Only He knows what is best for our marriages and families. It is by following God's will that we can work to build a culture of life... and what is more beautiful than that?
