(Prabhupada's lecture - Śrīmad-Bhāgavatam 1.16.21 - Hawaii, January 17, 1974)
So, there is a process how to appreciate, how to become qualified to appreciate, and that system is called varṇāśrama-dharma, to divide the whole human society into four classes of men: the brāhmaṇa, kṣatriya, vaiśya and śūdra. And those who are not regulated, they are pañcamas, below the śūdras. So the, our subject matter was unlawful meat-eaters. So even the śūdras, who are meat-eaters, they're lawful meat-eaters. What is that lawful meat-eating? Lawful meat-eating is... In any religion, formerly, even the Muhammadans or Hindus or the Jews, they used to kill one animal as sacrifice. They used to kill. Not in the slaughterhouse. Even up to date, those who are strictly religious followers... Suppose the Muhammadans. There in the Koran, the injunction is that "You should sacrifice one animal in the mosque."
The Jews also, they sacrifice animal in the synagogue. I have read one book, Lord Jesus Christ, when he was a young boy he was very much shocked when he saw that animal-killing is going on in the synagogue. Therefore he differentiated from the Jews and he started his own religion, Christian religion. Is it not a fact? Am I right? Why... He was also a Jew. Why he deviated? Why he deviated from the Jews? Because when he saw in his young age that animals are being killed in the synagogue, he differed, "No, no, this is horrible. This should be stopped." Therefore, his first commandment is "Thou shall not kill." Am I wrong or right? Eh? That was his first impression, that people should stop killing. So who is Christian? Everyone is violating this first commandment, what to speak of other commandments. Everyone. So it is very difficult to find a real Christian. But if you violate the commandments of Christ, then what kind of Christian you are? This is our question. Who will answer this?
