I found this painting of the Sacred Heart of Jesus on the web site of a Catholic Church in Indiana, U.S. There is nothing there to say who painted it. As an amateur artist myself, I have tried - unsuccessfully - to produce my own images of the Sacred Heart. It is notoriously difficult to produce a good one - either the face is wrong or the depiction of the Heart is wrong (too small, too clinical, too off-putting etc). I suppose the devotion of the Sacred Heart is most often associated with "Catholic kitsch". The painting above is one of the best modern depictions I have seen; it does not try to do anything other than be a simple attempt to to encourage devotion. It is tasteful, clear and approachable.
Like many Catholics of my generation (born 1948) and before, the Sacred Heart has been a major influence in my life. I was brought up in a parish dedicated to The Sacred Heart and St. Bernard (so there was a Marian connection through the saint). I remember looking up to a small stained glass window high above the altar - a window containing a traditional 19th century depiction of the Sacred Heart. It was, and remains, beautiful. Our Lord is holding out His arms in blessing and greeting. When I was a young priest, I enthroned the Sacred Heart in the home and personally wrote the names of my parents (now both deceased) and brother and sister, and signed it as the priest enthroning it. That picture now hangs in my presbytery bedroom. On the picture, the words of the enthronement speak about the parting that will come with death, but as we are reminded in the Funeral Mass, this parting is neither complete nor lasting. I am a great advocate of the Enthronement.
When I first began to read the writings of Vassula Ryden (True Life in God) I had the distinct impression that the Person I had known all my life and grew to love as a Friend - the Sacred Heart of Jesus - was "speaking" there. I still have this very strong impression when I read those "messages" and I find nothing there incompatible with the faith I had as a child and grew into and studied later as a seminarian.
Below is another reminder of my childhood and the importance of the devotion - Regina Nathan, the extraordinary Irish soprano, singing "Sweet Heart of Jesus"
