It strikes me, concerning the liturgical calendar, how our whole lives are being sanctified within its ritual.
(Whoa, I see that flag. Yes, I see that red flag in the front. And I see several in the balcony. Red flags are popping up all over the place at the mention of liturgical calendar and ritual, and cords of wood are being gathered as I speak of sanctification occurring in ritual. But hold off on the matches for a moment, if you would.)
What I mean by my statement is that when we live our lives consciously within the liturgical calendar, within liturgy, our lives begin to keep step with the Church. The patterns of the Church then become the patterns of our lives. Every Friday becomes not, principally, about the weekend, but a remembrance of Jesus' passion and death. We become participants in the life of Christ when we become participants in the life of the Church.
And through this participation we receive grace, not because of some magical mumbo-jumbo, or because of something we have earned, but because we have become fixed upon our God - the source of all graces. By His grace, we participate in His life and so become more like Him. (It is not a matter of 42 years of liturgical participation + 5,000 Eucharists + 1 baptism + 1 confirmation + 600 reconciliations + 1 anointing of the sick = a justified life. It is not mathematics or economics, but it is friendship with Christ - which leads to repentance and reconciliation and peace.) And as Moses' face shone from YHWH's presence, so our lives begin to shine in the presence of Christ and as His Body.
Fridays fix our minds on the resurrection we celebrate on Sundays. And so - week after week, season after season, year after year - our lives begin to beat with the rhythm of Christ's.
