Absolutely, though, as you said, things “should” be done the proper way. Personally, I try not to make judgments about individual people and what they do, rather considering trends and general concepts and how they affect my family and the Church. For instance, perhaps 10% of the people in our parish, of any age, genuflect at any time. Are they all injured? I doubt it, and I think this reflects a trend away from Catholic reverence and identity, and that affects all of us. My son is an altar server and has been taught not to genuflect when entering the sanctuary, but rather to bow to the altar. Do they clarify that this only applies during the Mass? No, and as such the people in the parish are slowly being taught to bow to the altar in churches and not to genuflect to the tabernacle. This leads to indifference to the Sacramental presence of our Lord, and therefore more and more we see conversations in churches before and after Mass, to the point where it is virtually impossible to pray. As St. Paul might have said: Haven’t these people houses to talk in?
Please don’t get me wrong. These people are probably ignorant, and may not be sinning in anything they do. I pray they aren’t. But, it doesn’t make a wrong a right in any way. It doesn’t negate the dangerous precedent of indifference and languid expressions of reverence.
As for genuflexion on the wrong leg, the interesting thing is I don’t think I have ever seen anyone but young people do this. I naturally assume they haven’t been taught better, and that prompts one to wonder why? Can a parent, I ask, truly care about showing reverence and not teach it correctly? It is just as the situation above. Can people really believe that the Sacrament is the Body and Blood of our Lord and pay no attention to it at all when entering and leaving a church? Do they sin? I haven’t a clue, and cannot really worry about it. What is a real problem, though, is trying to be attentive in a time when attention itself is seen an evil. But, as a parent and a Catholic I feel compelled to try to do things well and right to the best of my ability, and to do that I first have to know how. Those kids who genuflect on the wrong leg need somebody who cares to show them the right way before they can do it. I insist my children do things right, genuflecting on the correct leg, using the correct hand in making the sign of the cross, in keeping silent before the Sacrament, and so on. That isn’t mere legalism, but care. There is no such thing as careless reverence, and God, as you note, is surely pleased with an attitude of reverence.
