The answer is surely obvious to one as intelligent as yourself. My issue is with the false equation of ‘formal’ with ‘reverent’ and the resulting creation of a false dichotomy between ‘informal’ and ‘reverent’.
To me, all the formalities we indulge in, be they in matters religious or secular, in attitudes to dress for work play or church, all smack quite strongly of one thing above all - pandering to human respect. Which, while necessary (or at least desirable) to a limited extent, can quite easily be taken to unhealthy extremes like anything which is good in moderation. As in the ‘the Vatican wouldn’t let you in dressed informally’ comment earlier - which is an easily falsifiable presumption.
To me - well WHY would I dress for God as I would for the President? It’s somewhat belittling God, to my way of thinking, to imagine that He could as easily be swayed in his impression of me by fancy clothing as my fellow fallible human the President would be. And the argument that my dress might inspire me to greater reverence - well balderdash.
And my fellow humans? Well, all I know is that I’ve never been inspired to much of anything by the clothing choices of a fellow human being, although I often have been by things that they say or do otherwise.
So if you find that extra five minutes achieves something for you, more power and keep up the good work. For me, I’d far rather (as I do) get to church that five minutes earlier and spend the time in extra prayer, which I find benefits me and mine more than the stress of dressing up.
As I said earlier, Jesus used a very INformal term to describe God the Father, but His informality does not mean He was a jot less reverent than those around Him, some of whom doubtless had strong opinions about His daring to use the word ‘Daddy’ to describe the Deity.
