Emmett,

I am not sure of your background or your formation, but it's not very substantial for a priest.

The very idea of father and mother came from God.  It's an aspect or attribute of His nature.

It's embedded in our nature.

In a way it's a homing signal embedded in us to ever attract us toward God.

And of course fatherhood and motherhood (if well lived) solve lots of practical problems for the children of God.

And even the relationship between child and God is infinitely beneficial to us struggling souls.

It keeps us humble, leaving space in us for God to rush into us, to help us.

Ego and vanity crowd out God and His goodness.

I think there was part of one of the readings of today's or yesterday's Mass that referred to this.
