Jesus is LOVE and LOVE is teaching and warning the hypocrites that what they are taught through 'man made teachings' do not produce a heart for HIM and their praise of Him is in vain. There is no greater LOVE as Jesus died for those hypocrites but evil/man came to deceive them.
No doubt that God is love and is loved. The Father loves the Son and the Son the Father and the love shared between them is the Holy Spirit. Similarly, the love God has for us is Grace, and our love of God is latria. All have specific and deep meanings. But to say that Jesus is love expresses an understanding or concept of the Trinity that begs further explanation. Please elaborate.
That said, you still have not told me what St. John was telling us in the opening of hid Gospel when he referred to Jesus as the Word.
Peace and blessings
