So, then, if with Christ you've put all that pretentious and infantile religion behind you, why do you let yourselves be bullied by it?
"Don't touch this! Don't taste that! Don't go near this!"
Do you think things that are here today and gone tomorrow are worth that kind of attention?
Such things sound impressive if said in a deep enough voice. They even give the illusion of being pious and humble and ascetic. But they're just another way of showing off, making yourselves look important.
