Parents, children, and sin

Heidelberg Catechism
Q & A 7
Q. Then where does this corrupt human nature come from?

A. From the fall and disobedience of our first parents,
Adam and Eve, in Paradise.¹
This fall has so poisoned our nature²
that we are born sinners—
corrupt from conception on.³

Note: mouseover footnote for Scripture references.

Our first ancestors fouled the well, and poisoned our inheritance. Kuyvenhoven puts it well, I think, when he says (27),

[The catechism] intentionally calls Adam and Eve our “parents,” thereby teaching that, just as black parents get black children and white parents get white children, so sinful parents get sinful children, whether they are yellow, red, black, or white. None of us can escape this poison, for all of us have parents. That’s the teaching.

And none of us can avoid passing it on, for all of us are sinners. As the father of three, I can testify that I am far more aware of my own depravity now than I ever was before they came along.
