According to the letter of St. Paul to the Galatians, St. Paul lists out the specific “fruits” of the Holy Spirit, “the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such there is no law” (Galatians 5:22-23).
However, the Catechism of the Catholic Church defines this fruit as “perfections that the Holy Spirit forms in us as the first fruits of eternal glory” (CCC 1832).
Primarily, if we are living a “life of the Spirit,” these “fruits” will definitely be found in our lives.
Though, most translations of the above passage only enlist nine fruits, while the Latin Vulgate provides a list of 12 fruits, adding modesty, generosity, and chastity.
But the fruit of the Spirit as we know it is, charity, joy, peace, patience, benignity, goodness, longanimity, mildness, faith, modesty, continency, chastity. And against such there is no law (Galatians 5:22-23).
So, according to the Catholic Encyclopedia, “there is no doubt that this list of twelve — three of the twelve are omitted in several Greek and Latin manuscripts — is not to be taken in a tight limited sense, but, according to the rules of Scriptural language, as capable of being extended to include all acts of a similar character.”
Having this in mind, the Catholic Church has accepted these “extra” fruits and lists them in the Catechism, “The tradition of the Church lists twelve of them: ‘charity, joy, peace, patience, kindness, goodness, generosity, gentleness, faithfulness, modesty, self-control, chastity’” (CCC 1832).
St. Thomas Aquinas went further to defend this expanded list in his Summa Theologiae.
The number of the twelve fruits specified by the Apostle is suitable, and that there may be a reference to them in the twelve fruits… As Augustine says in Galatians 5:22-23, “the Apostle had no intention of teaching us how many [either works of the flesh, or fruits of the Spirit] there are; but to show how the former should be avoided, and the latter sought after.”
Though either more or less fruits might have been mentioned.
But at the same time, the Catechism also mentions the nine fruits of the spirit in a different paragraph, (CCC 736) “By this power of the Spirit, God’s children can bear much fruit. He who has grafted us onto the true vine will make us bear ‘the fruit of the Spirit:… love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control.’
‘We live by the Spirit’; the more we renounce ourselves, the more we ‘walk by the Spirit”.
In reality, the actual “number” of fruits is not something we need to focus on. As Christians are called to live a life of the Spirit, producing much fruit which is shown through our thoughts, words and deeds.
This is the same meaning that St. Paul is going for, as he spells out the nine characteristics as, simply, fruit (singular) of the Spirit.
However, the difference in number and lists might make memorization hard, however, it is a reminder of God’s real message to us.
As Jesus said to his disciples, “By their fruits you shall know them” (Matthew 7:16).
