Other early Christian historical documents observe that many influential Christians during the formative centuries of Christianity were vegetarian, though certainly not all.
Christian vegetarianism is a Christian practice based on effecting the compassionate teachings of Jesus, the twelve apostles, and the early church to all sentient or living beings through vegetarianism or, ideally, veganism.
Alternatively, Christians may be vegetarian for ethical, environmental, nutritional, or other spiritual reasons.
