The great feast of the Sacred Heart of Jesus and with that the opening of the Year of the Priest (June 19), ought to be a time for us to focus on our study and prayer on the mercy and medicine offered to us by the Lord. Why is this feast an apt time for us to focus our energies on the theology of the Sacred Heart? Because as the psalmist says, seek His face; it is a true school of the Lord’s love. I believe, as you might, that the feast of the Sacred Heart is a propitious time to come to understand the wisdom and knowledge of the Divine Heart.
Father Richard Neilson’s 1988 article “The Sacred Heart and the Eucharist” is a good place to start.
