If Paul and Peter were vegan, surely they were inspired by Jesus who was most likely a vegan!
Reading this article by Richard Angelin helped me to be able to refute a number of arguments that Christians use to persuade me that being a vegan is unbiblical. I encourage you (and me!) to really study this. Studying complicated stuff helps keep your brain elastic and youthful, just in case you need incentive! And even more importantly is for us to be able to help Christians to study their Bible in a way that might open their eyes to the truth–that Jesus and leaders in the early Christian church–preached and practiced veganism.
