I have visited many beautiful and magnificent cathedrals, basilicas, and churches which are big tourist attractions. Examples are Notre Dame of Paris and St. Peter's Basilica in Rome. People flock there to see the impressive architecture, sculptures, murals, paintings, etc., but I would be surprised if many visitors actually felt drawn to Christ during their visit. All the attractions can easily become distractions. I attended Mass at one church in Escondido, CA, once. The singer was so good that it made me focus on the singing more than on the Lord. Over a decade ago, I attended daily Mass at a nearby seminary. The Mass was held in a small chapel with an altar and some stained glass windows. There were not even regular pews. So it's a rather spare place. Yet in remaining at the chapel alone after Mass, I experienced many spiritual breakthroughs. Now this chapel had been fully furbished with pews, red carpet, improved lighting, etc. and looks beautiful. Somehow I miss its former spare look which was less distracting. I had mentioned that I felt the intimacy of God most when I woke up late at night or very early in the morning when it's quiet and dark. So the best way to experience God is to be in solitude without any distraction, leaving only you and God alone together. The world does not know God because it is being distracted by all sorts of things not of God.
