Where does it not?
Did Christ love the brethren?
See Ro 13:8; Gal 5:1.
Was Christ the fullness of God?
See Jn 1:14, 16; Col 1:19, 2:9; Eph 1:23, 3:19, 4:13.
I'll leave the parsing to you.
I was kinda hoping you would...
Rom 13:8 Owe no one anything except to love one another, for he who loves another has fulfilled the law.
Rom 13:9 For the commandments, "YOU SHALL NOT COMMIT ADULTERY," "YOU SHALL NOT MURDER," "YOU SHALL NOT STEAL," "YOU SHALL NOT BEAR FALSE WITNESS," "YOU SHALL NOT COVET," and if there is any other commandment, are all summed up in this saying, namely, "YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF."
So fulfilling the law in this case means that love is the summation of the Commandments, not the doing away of them.
Gal 5:1 Stand fast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage.
Fulfillment is not in this verse, you are obliquely references something that was not meant here but since you have, let's read the entire passage instead of lifting it out of context...
Gal 5:1 Stand fast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage.
Gal 5:2 Indeed I, Paul, say to you that
if you become circumcised, Christ will profit you nothing.
Gal 5:3 And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law.
Gal 5:4 You have become estranged from Christ,
you who attempt to be justified by law; you have fallen from grace.
Paul here is referencing physical circumcision and then explaining that physical circumcision does not justify us. I have never said that physical circumcision justifies us, we are justified by His blood, but not saved by it...
Rom 5:9 Much more then, having now been justified by His blood, we shall be saved from wrath through Him.
WE are saved by His life.
Christ being the fulness of God is not the question but since you referenced it...
Joh 5:37 And the Father Himself, who sent Me, has testified of Me. You have neither heard His voice at any time, nor seen His form.
Joh 6:46 Not that anyone has seen the Father, except He who is from God; He has seen the Father.
No one has seen or heard the Father at any time, but Adam and Eve heard and saw someone...
Gen 3:8 And they heard the sound of the LORD God walking in the garden in the cool of the day, and Adam and his wife hid themselves from the presence of the LORD God among the trees of the garden.
Abraham heard and saw the LORD, but it was not the Father...
Gen 17:1 When Abram was ninety-nine years old, the LORD appeared to Abram and said to him, "I am Almighty God; walk before Me and be blameless.
All Israel heard someone, but it was not the Father...
Exo 20:1 And God spoke all these words, saying:
Who was this?
1Co 10:1 Moreover, brethren, I do not want you to be unaware that all our fathers were under the cloud, all passed through the sea,
1Co 10:2 all were baptized into Moses in the cloud and in the sea,
1Co 10:3 all ate the same spiritual food,
1Co 10:4 and all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ.
This was Jesus Christ. So, help me out, is He schizophrenic? Does He have a split personality or did He really mean what He said here...
Luk 16:17 And it is easier for heaven and earth to pass away than for one tittle of the law to fail.
Did He do away with His own Law? Did He make a mistake with the Ten Commandments and have to come in the flesh to fix this?
Or is the Law exactly what Paul says...
Rom 7:12 Therefore the law is holy, and the commandment holy and just and good.
Rom 7:14 For we know that the law is spiritual, but I am carnal, sold under sin.
And do we do away with the Law?
Rom 3:31 Do we then make void the law through faith? Certainly not! On the contrary, we establish the law.
