I remember the first shot I took in a basketball game. I missed. Thankfully. I remember the noise of the crowd heckling us (we were the away team), particularly after my less than stellar attempt to make a basket after hustling for a rebound.

To my surprise, everyone was running the other way and my shot went off with little to no block attempts by the other team. This only makes sense, since I had just earned a defensive rebound only to lob the ball back up at our opponent’s goal.

Such embarrassing moments are not limited to the court of organized children’s sports, but can be an unfortunate reality in Christian apologetics.

In my office, I have a large print of Augustine (the image used with this blog post). His heart is ablaze for truth, illustrated by the Latin word “veritas.” The seventeenth-century painting is a reminder to me that sharing and defending the gospel requires both head and heart. And the following excerpt from Augustine’s teaching, quoted by John Lennox in this video, reminds me that it also necessitates careful scholarship and wise speech:

“Usually, even a non-Christian knows something about the earth, the heavens, and the other elements of this world, about the motion and orbit of the stars and even their size and relative positions, about the predictable eclipses of the sun and moon, the cycles of the years and the seasons, about the kinds of animals, shrubs, stones, and so forth, and this knowledge he hold to as being certain from reason and experience.

Now, it is a disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the meaning of Holy Scripture, talking nonsense on these topics; and we should take all means to prevent such an embarrassing situation, in which people show vast ignorance in a Christian and laugh it to scorn. The shame is not so much that an ignorant individual is derided, but that people outside the household of faith think our sacred writers held such opinions, and, to the great loss of those for whose salvation we toil, the writers of our Scripture are criticized and rejected as unlearned men.

If they find a Christian mistaken in a field which they themselves know well and hear him maintaining his foolish opinions about our books, how are they going to believe those books in matters concerning the resurrection of the dead, the hope of eternal life, and the kingdom of heaven, when they think their pages are full of falsehoods and on facts which they themselves have learnt from experience and the light of reason?

Reckless and incompetent expounders of Holy Scripture bring untold trouble and sorrow on their wiser brethren when they are caught in one of their mischievous false opinions and are taken to task by those who are not bound by the authority of our sacred books. For then, to defend their utterly foolish and obviously untrue statements, they will try to call upon Holy Scripture for proof and even recite from memory many passages which they think support their position, although they understand neither what they say nor the things about which they make assertion.”
