who engages in the study on the Trinity knows the difficulties. Who has been enlightened by God and has made a contribution in this direction is not always definitive conclusions arrived at. There is no Nobel prize in that sense ... Trinity remains an ineffable mystery of Love. The best attitude is surely to be respectful and silent adoration towards the One who is One in essence but three in Persons.
God is not alone. If it were just the love would not make sense: you can love yourself? Love needs to be addressed to someone ... If we are made in the image of the Trinity we must love.
Glory to the Father, the Son and the Holy Spirit, as it was in the beginning, now and ever, forever and ever. Amen.
