Taken from the St. Andrew Bible Missal:

Wasted time is not a prized commodity in American society. We are a people ruled by the clock. Time is money because time is to be filled with purposeful controlled activity which is productive of things which can be sold. We are convinced that we must be in control of time. The last thing the productive American would want to do is waste time playing around with realities that do not produce a saleable commodity.

But the Creator of heaven and earth is described by the Scriptures as the original and the best of players. Creative activity is playful and creative people do not feel that what they do is a job. Creative people also have a sense that their creativity and all that they fashion in the creative spirit are gifts they have received. The Christian can speak of this and the contemplative vision which sees all reality as gift or grace. Our thankful response we call worship or eucharist.

We cannot speak of Ordinary Time without speaking of Sunday. The every seven-day celebration of the Lord’s Day is the basic structure upon which the Church year is built. The great liturgical seasons of Advent-Christmas and Lent-Easter are more expansive celebrations of particular aspects of the one paschal mystery which we celebrate every Lord’s Day. These special seasons focus our attention upon critical dimensions of one mystery, a mystery so overwhelming that we are compelled to separate out its various elements for particular attention. These seasons in no way minimize the critical importance of the Sunday celebration throughout the rest of the year.

Ordinary Time is not very ordinary at all. Ordinary Time, the celebration of Sunday, is the identifying mark of the Christian community which comes together, remembering that on this first day of the week the Lord of Life was raised up and creation came at last to completion. Sunday as a day of play and worship is a sacrament of redeemed time. How we live Sunday proclaims to the world what we believe about redeemed time now and forever.

What happens in our churches every Sunday is the fruit of our week. What happens as the fruit of the week past is the beginning of the week to come. Sunday, like all sacraments, is simultaneously a point of arrival and departure for Christians on their way to the fullness of the Kingdom. This is not ordinary at all. This is the fabric of Christian living.
