The correct way to say it and so it agrees with Christ is this. The whole law is summed up in one
word which is love. The law is summed up by love, but not love thy neighbor alone.
Galatians 5:14
New King James Version (NKJV)
14 For all the law is fulfilled in
one word,
even in this: “You shall love your neighbor as yourself.”[

Mt 22:
36 “Teacher, which
is the great commandment in the law?”
37 Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’[
d] 38 This is
the first and great commandment. 39 And
the second
is like it: ‘You shall love your neighbor as yourself.’[
e] 40 On these two commandments hang all the Law and the Prophets.”
