Great Commandment

The Great Commandment is a term used to describe the first of two commandments cited by Jesus in  Matthew 22:35–40,  Mark 12:28–34 and Luke 10:27

The great commandment and the other commandment that is spoken just under it in Matthew 22:39 and Mark 12:31 are in response to an unnamed Pharisee, who was described as a scribe, or lawyer. This scribe/lawyer was testing Jesus, trying to trick Jesus into saying something disreputable, or scandalous according to their religion. Jesus responded by saying the greatest commandment was "And you shall love the LORD your God with all your heart, with all your soul, with all your mind, and with all your strength. This is the first commandment. And the second, like it, is this: You shall love your neighbor as yourself. There is no commandment greater than these." (Mark 12:30-31)

In Matthew 22:40, Jesus explains the reason behind these being the greatest commandments; one, or both are the root of all the other commandments that are given to his followers.

Quotes about the Great Commandment

• Jesus ... combines all duties (1) in one universal rule (which includes within itself both the inner and the outer moral relations of men), namely: Perform your duty for no motive other than unconditioned esteem for duty itself, i.e., love God (the Legislator of all duties) above all else; and (2) in a particular rule, that, namely, which concerns man’s external relation to other men as universal duty: Love every one as yourself, i.e., further his welfare from good-will that is immediate and not derived from motives of self-advantage. These commands are not mere laws of virtue but precepts of holiness which we ought to pursue, and the very pursuit of them is called virtue.
