Ordinary Time means normal time. Everything in the Church’s calendar up to now (Christmas, Easter, Pentecost, etc.) has Ordinary Time as the goal. The focus of Ordinary Time? Jesus’ public ministry – his direct outreach to humanity and the reason for calling him “Emmanuel” (literally “God with us”).
The Old Testament readings remind us of God’s promise of a savior, and the verses leading up to Sunday’s Gospel show us that Jesus is the fulfillment of God’s promise. Sunday’s Gospel makes it clear that Jesus’ fulfillment will be in accordance with God’s plan, not our expectations.
The first half of the Gospel can sound like this fulfillment is by invitation only. If that’s the case, then you should probably read the second half of the Gospel – it has your invitation, and it’s probably not what you were expecting.
This Gospel begins the unfolding of Ordinary Time – the Church’s idea of normal – to show us the savior who is not what we expected, but everything that we need.
