For more on this, see the New Advent Catholic Encyclopedia article on the Holy Ghost, section VII, Fruits of the Holy Ghost.
Charity is our love for God above all things for His own sake, and our neighbor as ourselves for the love of God. Jesus told His apostles, Jn 13:34 Love one another; even as I have loved you, that you also love one another. By this all men will know that you are My disciples, if you have love for one another. St. Paul told us, 1 Cor 13:13 Faith, hope, love abide, these three; but the greatest of these is love. Charity is a gift to us from God, wrapped in sanctifying grace. Charity, like hope, resides in the will.
Charity is one of the three theological virtues. The others are faith and hope.
Charity is also one of the twelve fruits of the Holy Spirit.
God Bless.
These extra "virtues" are, in my opinion, superfluous.
