400 years ago, life for the average person was slower and more even-keeled and less busy. A person might stay in the same town for their entire lives, and the rhythms of daily life were dictated by the seasons, and followed a regular pattern from day to day and year to year.
I can see why receiving Holy Communion less frequently would be OK back then. So little changed from year to year. Life passed slowly, and life was finished in 30 years.
But in 2014, life moves at a frenetic pace, and for most of us, the rhythm is erratic and jarring and stressful. We try to plan, and then all our plans go awry due to circumstances out of our control. There is no regular pattern. Each day brings new crises, new stresses, new tragedies and also, new joys, new highs, new wonders. Each week, we hear about a new invention, and many of these inventions make our communications even faster and make the world smaller and smaller. Travelling the world and even outer space (by the rich) is becoming the norm, and even those who don’t physically travel anywhere can visit via media. Life is a wild ride, and for many of us in the U.S., at least, that ride lasts for many decades.
I think that in this frantic day and age, with so many changes from moment to moment, it is good for us to frequently receive Jesus in Holy Communion at the Mass. We need Him.
