Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
I take two buses and two light rail trains to get the 20 miles one-way to Liturgy, and I leave an hour and a half early to get there. I am English about my timing, if you're not ten minutes early you are late! I have had several nervous breakdowns when missing a bus or train or otherwise finding myself late, especially after having worked so hard and dilligently to get there on-time. However, even in my own experiences with being late, I've come to learn from experience that it isn't all or nothing. We have to understand that it is God who brings us to Church any time, as it is God who even gives us life and drags our derrieres out of bed each morning
We learn to let GOD takeover and do the work, and we respond by cooperating as best as we are able, letting God do His thing while trying our bests to match His effort.
If folks have made it their routines to get there habitually late, such as by this Gospel reading or by that particular prayer, I'd discourage that kind of behavior. The purpose of Church is to challenge us, to push us in our Faith, that we can grow and spiritually mature in our relationship with God by the experience, just as in our own families and lives experience pushes us in many directions. So when folks are randomly late to Liturgy, that is fine, hopefully in prayer they are feeling repentant about their priorities and will push themselves to make amends in the future. For those who stumble in routinely late with this or that excuse, such flippancy is hardly spiritual growth. I would never be mean-spirited or condescending to such folks, but I can't help but spiritually pity them that they are not allowing the Church to push them to grow more and more each day in their lives. Sunday Liturgy is a weekly opportunity for us to challenge ourselves and to grow each week, it is not just an empty obligation. Further, we grow as a community the more we harmonize and get on the same page. I love Catholic parishes, but from my experience, they don't seem to be as intimately interconnected as Orthodox parishes, and I pray we keep up our efforts unless we become some of the more lax Catholic parishes which over emphasize the Universal Church and not the family of Christians coming together as One Body of Christ. Can the foot show up fifteen minutes later than the hand?
Further, if we show up to work and school on time day in and day out during the week, can't we value our opportunity to come to the Kingdom of Heaven on Earth and stand in prayer before Our Lord and Savior Jesus Christ? The prayer which drags my lazy behind out of bed each Sunday to hit that train is, "ARE YOU NOT STRONG ENOUGH TO STAND AND PRAY WITH ME FOR ONE HOUR? The spirit is willing, but the body is weak, so pray to the Father.."
