Sorrow can be alleviated by good sleep, a bath and a glass of wine. — St Thomas Aquinas.

Mark 8:14-21 — Wha?

I meant to ask this yesterday but I forgot: the Gospel reading for yesterday’s Mass, Mark 8:14-21, has me completely perplexed. I don’t know what it means at all, and it’s especially frustrating that it ends with Jesus saying “Do you still not understand?” No, I’m as mystified at Jesus’s statement and questions as the apostles probably were.

I listened to this reading on podcast, and not at Mass, so I don’t have the benefit of the accompanying homily. Someone show off your exegesis sk1llz and elucidate this for me, please!
