There's an old adage that offers a wise counsel, even as it leaves us powerless to heed its advice: Pick your parents wisely!

Easier said than done, but the adage holds. We're not fully our own persons. We're also products of our parents who give us not only our physical DNA, but — in complex confluence of how they are inside their own persons and how they relate to us and to the world — also profoundly help shape our person and our character. As adults, it can be both freeing and emotionally-crippling to reflect upon exactly what we really inherited from our parents. They shape us.

I have this in the back of my mind today, Mother's Day, as I reflect upon my own mother and the DNA that I inherited from her. She died 43 years ago but she left a lot of herself here, with my siblings, with me.

What she gave me didn't happen in a vacuum. She raised a large family, with the help of a very supportive husband, my dad, and, while they had a marriage made in heaven, they had to spend most of it chronically strapped for money, time and energy. The demands on her were always somewhat beyond that for which she had adequate resources.

But somehow, she always managed to make do, always found a way to stretch everything, including her time and energy, to feed, clothe and properly mother us.

She frequently didn't have the time, energy or heroic patience to provide us with the individual affection and warmth that a child so desperately desires and needs, even though she was a naturally warm and kind-hearted person. The pressure of so many needs could wear her idealism and attention pretty thin at times.

And so she wasn't a Hollywood mom, always perfectly dressed and perfectly affectionate. But she gave us, and in spades, the most important thing that a home is really asked to give, safety and security. The one need in a child that trumps all others is the need to feel safe and secure. My mother was often torn in so many directions, but she did provide us with what we needed most of all. She gave us a house and a home that was always steady and robustly sane — often times, loudly so. Inside that ambience we were always safe. Nobody could have given me a greater gift or greater riches in my youth.

Moreover, inside all that busyness, scrambling to provide, and the conscriptive attention deficit disorder that she had chronically to deal with, she taught us something else of importance, namely, that you don't have to wait until everything is perfect, until all your bills are paid, your health is perfect, you have the right leisure time, and there are no large headaches waiting for you tomorrow, in order to celebrate and enjoy a moment.

She knew how to celebrate the temporary. Every feast-day, birthday or Sunday was an occasion for a special meal and a special celebration no matter whatever else might be putting a damper on life. And, perhaps most important of all, my mother was largely responsible for giving me faith, though, in this, she had my dad as an equal partner. But she, more than anyone else, pushed me to be open to hear the call to priesthood.

Anthropologists who study initiation rites in various cultures tell us that the initiatory process needed to move someone from being a child to an adult needs to instill four salient truths: Your life is not your own. Life is hard. You will die. Your life is not about you.

The culture and church out of which she came had already indelibly etched those truths into her. For her generation, especially if you were poor and lived in a rural area, life was naturally hard and mortality rates were high. Lots of people died young. And the ethos of her generation held that family, church, neighbor and country could ask you for your life, and your duty was to give it over, without whining or self-pity. It was selfish to think first of yourself.

She had inhaled that ethos and then she etched it into us, particularly the truth about your life as not being about you. The other facts, that life was hard and that you were going to die, were left to speak for themselves, but from the time you graduated from toys to school, the message was clear: Your life is not your own. Your life is not about you. Anthropologists might well study my mother's initiatory vision and tactics.

No mother is perfect, and neither was mine. She had her faults and I carry many of those too, along with the better things she gave me. But, reflecting on my mother, I have only good feelings and warm gratitude. I chose my mother wisely!
