But Jesus didn't actually say that! Shock! Horror! It was the expert in the Law who says them. Jesus agrees with the answer (Lk. 10.28), but he’s not the one who actually puts forth that translation of Deuteronomy 6.5. In Matthew 22.37 Jesus does say “Love the Lord your God with all your heart and with all your soul and with all your mind” and in Mark 12.30 he says “Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.” (NIV2011) We have in the Gospels three citations of Deuteronomy 6.5 (two of them spoken by Jesus) and each uses different wording.
But regardless of whether or not these are accounts of the same event, we don’t necessarily have the exact words that Jesus spoke, or even know if they were originally in Hebrew, Greek or Aramaic. The gospel authors record Jesus’ message in Greek (a dynamic translation?) but for the most part we simply don’t know precisely what Jesus said. The message that the Gospel writers are trying to convey is that Jesus replied by quoting Deuteronomy 6.5:
Deuteronomy 6:5
You must love the LORD your God
with all your heart (leb),
all your soul (nephesh),
and all your strength (me’od).
You must love the LORD your God
with all your heart (leb),
all your soul (nephesh),
and all your strength (me’od).
Luke 10:27
You must love the LORD your God
with all your heart (kardia),
all your soul (psyche),
all your strength (ischus),
and all your mind (dianoia).
You must love the LORD your God
with all your heart (kardia),
all your soul (psyche),
all your strength (ischus),
and all your mind (dianoia).
These commandments captures the essence of who we are. We can’t fully love God, we can't fully love ourselves or others, if we only love emotionally, we can’t fully love if we only offer intellectually support — we can only truly and fully love [God] if we do so with everything we have.
These commands aren’t simply feel-good platitudes, they are a powerful call toembrace a specific and active love. The realities of life challenge love at every turn, and love alone, as a disembodied feeling adrift on the Platonic ether, cannot save us. But love as a practice, love as a way of life, love as an experience of God, love that encompasses the totality of God’s plan — that love can save us. Love requires participation, it requires maintenance, it requires attention: “Above all, maintain constant love for one another, for love covers a multitude of sins” (1 Pet. 4.8).
Love doesn’t obviate other aspects of a Christian life, love holds those aspects together. Love is not a solitary requirement, it is the thread that unifies and empowers all the other requirements. If we don’t have love, nothing else works. If we don’t show love, we can’t expect to receive it. If we don’t love God, how can we hope to love our neighbor? “But love your enemies, and do good, and lend, expecting nothing back. Then your reward will be great, and you will be sons of the Most High because he is kind to ungrateful and evil people. Be merciful, just as your Father is merciful” (Luke 6.27–36).
Love is a means of relationship - not only between human beings, but between humans and the rest of nature. Having been privelaged to be at the birth of my kitten and seeing the love, the nurturing between the new mother and her kittens, and between Ginger - my kitten - and myself there is more than just just chemical impulses and pheremones. Love is also the means by which the Divine, all that is Holy can be related to.
“All you need is love” may be inaccurate in a strict sense, but to those who accuse some of us of putting an inordinate amount of emphasis on love, one must remember that it was Jesus himself who set the precedent. Love, properly enacted and expressed, subsumes the distractions of theology and overpowers our personal tendencies to judge and criticize.
