I personally have far more important things to focus on than whether attire might or might not be appropriate.
Except that it was you who focused on it; so apparently it is very “important” to you. You drew a strained relationship between outreach and attire, which makes it appear that you associate casual clothing with superior charity (and/or more pure intentions); more formal clothing with inferior charity (or more suspect, less pure intentions). They are not related. There is no reason to bring up clothing, and you brought it up – no one else.
"God works within us to show His love regardless of what we wear to Mass".
…in which case there is no purpose in interjecting the topic artificially, because it is “regardless” –
without regard.
But I want to loop back to the recent discussion on fellowship, and assumptions made in earlier posts about who should welcome whom (because it was introduced as a supposed “reason” for leaving the Church. Folks, it’s our individual responsibility to be welcoming individuals, or approachable individuals – people to whom others are drawn. Be very careful (aside from any positive or negative uncharitable association with clothing) about attaching value to the reluctance of strangers to extend themselves to other strangers.
I’ve attended Mass and sung in Mass choirs at dozens of locations; in general, most people are not naturally extroverted when it comes to complete strangers in a “crowd” at a formal event (Mass, funeral, wedding, even civic formal event). Most people keep to themselves, particularly when they do not know anyone else. This is particularly true among certain age groups (the very young, the very old). It’s immature to “demand,” even internally, that others extend themselves to us. If you are/we are so interested in “fellowship,” walk over to someone else (either at the exchange of peace, or more appropriately, after Mass) and introduce yourself or say Hello.
And be very careful of interpreting a serious look as a “glare,” or even as disapproving. Many people are not even comfortable at the exchange of peace, despite it being a structured moment, and certainly would not leave their seat, let alone pew, to extend themselves. It’s not an indication that they lack charity, warmth, or are lazy. It can be social habit, personality, fear, culture, or all of that. I recently sung at a parish dominated by those from a certain cultural group which is conservative and non-expressive. To those of us in the choir they “looked” unhappy – even “miserable,” regardless of any joyous words that were being sung. In their culture, it is bad form to be expressive at a solemn event, and just as bad form to extend particular gestures of “friendship” to complete strangers, even during an invited moment, such as the exchange of peace.
So now I sing at a different parish, and even despite a very different cultural configuration there, I find that still, most people do not show on their faces or in their body language and gestures how they really feel, and how they are responding to whatever is going on at Mass – be it the exchange of peace, the words in a hymn, the homily, etc. What I have learned is to stop assuming anything from people’s outward behavior, and to start taking the lead if I want to “connect” with people in a giving/receiving way. You need to give if you want to receive. That’s the way the world works.
So I don’t need to worry about someone’s private opinion of me or of others, as supposedly indicated by their lack of outreach. All I need to do is to walk over to that other person (in my pew, out of my pew at Masses in which I am not singing or taking a leadership role) and be the person to greet an apparent introvert warmly. I don’t deserve fellowship if I can’t give it first. I have never experienced that when
I am the one to extend myself by touching someone gently on the shoulder, or smiling warmly, they bristle or reject me. They are always relieved and touched by a gesture. That is true whether this is my first time inside that church or my 2028th time.
And as to the serious and supposedly unresponsive looks on faces when others in the chuch are animated, I have learned from comments after Mass that some of the people who look the most serious and reserved are the ones most appreciative and internally responsive to emotively sung music (for example), and to a well-prepared & powerfully delivered homily. It’s very unreasonable to demand that people show outwardly, in public, in front of strangers, what they are feeling inwardly – toward others, toward the priest, toward the music at liturgy, etc. It’s a structured, formal event; it’s not a party. Please remember that when you lament the supposed lack of “fellowship.” There’s not much opportunity for fellowship during Mass.
