I think you're pointing to a distinction that is often missed in both Catholic–Protestant debates.@Inquisitor
about obedience is the fruit;
John 15:1-7 is often quoted to speak about faith and remaining in Christ, but Jesus Himself connects abiding in Him with obedience.
First, notice what Jesus says:
“I am the true vine, and my Father is the husbandman... Every branch in me that beareth not fruit, he taketh it away... Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; so neither can ye, except ye abide in me.” (John 15:1, 2, 4 ASV)
Jesus teaches that a person must remain connected to Him, just as a branch remains connected to the vine. A branch that does not bear fruit is removed. The question then becomes: How do we abide in Christ?
Jesus answers that only a few verses later:
“If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.” (John 15:10 ASV)
This is the direct explanation of what abiding means. To abide in Christ is not merely to believe that He exists or to make a profession of faith. It is to continue in His words and keep His commandments. Jesus points to His own example: just as He remained in the Father's love by keeping the Father's commandments, His disciples remain in His love by keeping His commandments.
This agrees with what Jesus taught earlier:
“If ye love me, ye will keep my commandments.” (John 14:15 ASV)
And:
“He that hath my commandments, and keepeth them, he it is that loveth me.” (John 14:21 ASV)
And:
“If a man love me, he will keep my word.” (John 14:23 ASV)
So when Jesus speaks about bearing fruit in John 15, He is not speaking about a fruit that appears apart from obedience. The fruit comes because the branch remains attached to the vine, and remaining attached to the vine means continuing in His teachings and obeying His words.
This is why Jesus also says:
“If ye abide in me, and my words abide in you, ask whatsoever ye will, and it shall be done unto you.” (John 15:7 ASV)
Notice that Jesus does not simply say, "If you believe in Me." He says, "if My words abide in you." His words must remain in the heart and be lived out. Obedience is not separated from abiding; it is part of abiding.
The same truth appears elsewhere in Jesus' teaching:
“And why call ye me, Lord, Lord, and do not the things which I say?” (Luke 6:46 ASV)
And:
“Every one therefore that heareth these words of mine, and doeth them, shall be likened unto a wise man, who built his house upon the rock.” (Matthew 7:24 ASV)
John 15 therefore presents a simple but powerful picture: Christ is the vine, His followers are the branches, and the evidence that a branch is truly abiding in Him is that it bears fruit. According to Jesus' own explanation, this abiding is expressed by keeping His commandments, letting His words remain in us, and continuing faithfully in what He taught. A branch that refuses to remain in His words cannot continue to bear fruit, because obedience and abiding are inseparably connected in the teachings of Christ.
If we stay strictly within Scripture, especially the Johannine writings (John's Gospel and 1 John), the issue is not really:
Law vs. grace
Ten Commandments vs. faith
Catholic vs. Protestant
Rather, it is:
Old Covenant commandments (Sinai)
versus
New Covenant commandments (Christ)
And then a further question:
Is the "fruit" of John 15 primarily moral works, or is it the manifestation of the Spirit's life?
The New Covenant Commandment
Jesus does not say in John 15:
"This is my commandment: keep the Ten Commandments."
He says:
"This is my commandment, that you love one another as I have loved you."
Then John later writes in 1 John.
"This is his commandment, that we should believe on the name of his Son Jesus Christ, and love one another."
(1 John 3:23)
If Scripture is allowed to define Scripture, John's definition of Christ's commandment is remarkably simple:
- Believe in the Son.
- Love one another.
Not Sinai.
Not the Ten Words.
Not the Mosaic code.
Those may still contain moral truth, but John does not define Christ's commandment that way.
What Is the Fruit?
This is where a significant divide appears.
Many Catholics and Protestants alike tend to read "fruit" as:
- Good works
- Moral behavior
- Acts of charity
- Obedience
But another Scripture-only reading asks:
Where does Scripture explicitly define spiritual fruit?
The clearest definition is in Epistle to the Galatians 5:
love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control.
Notice that these are not activities.
They are qualities produced by the Spirit.
The text does not call feeding the poor "fruit."
It calls love fruit.
It calls joy fruit.
It calls peace fruit.
It calls patience fruit.
The works may flow from the fruit, but they are not themselves identified as the fruit.
The Catholic and Protestant Tendency
Despite their disagreements on salvation, Catholics and many Protestants often end up very close together here.
They commonly interpret fruit as:
- Visible deeds
- Moral performance
- External obedience
- Service
The difference is usually over why those works matter.
Catholics:
- Works participate in sanctification.
Protestants:
- Works demonstrate genuine faith.
But both frequently focus on observable conduct.
The Spiritual Reading
A more spiritual or mystical reading stays closer to John's language and Paul's definition of fruit.
The sequence becomes:
Abide in Christ → Receive the Spirit → The Spirit produces fruit → Fruit naturally produces works.
In this view:
- Fruit is not the work.
- Fruit is the inner life of Christ manifested through the Spirit.
A person can perform many religious works and still lack the fruit.
This is why Paul can say one may:
- speak in tongues,
- prophesy,
- move mountains,
and yet lack love.
The activity exists.
The fruit does not.
The Gulf
So the deepest gulf may not be Catholic versus Protestant.
It may be:
Institutional Reading
Commandments:
- Obedience requirements.
- Often understood through church teaching or moral law.
Fruit:
- Observable works and conduct.
Spiritual/New Covenant Reading
Commandment:
- Believe in Christ.
- Love as Christ loved.
Fruit:
- The life of the Spirit manifested within the believer.
- Love, joy, peace, patience, and the other qualities that the Spirit Himself produces.
Works are then the result of fruit, not the fruit itself.
End AI.
So Catholics and Protestants are very, very, similiar.
There both wrong.
