Excellent homily here from the pastor at the noon Mass. He touched on the three pillars briefly, but zeroed in on the passage from 2 Corinthians, especially this:
So we are ambassadors for Christ, as if God were appealing through us.
Those marks on your foreheads, he reminded us, are your ambassadorial credentials.
Lent has a baptismal focus (Sacrosanctum Concilium 109) as well as a penitential one, and certainly, the spread of the gospel, evangelization, and serving as a witness to and ambassador for Christ is all tied up in the baptismal theme. I won’t hear the Ash Wednesday readings again without being drawn to Saint Paul. Being an ambassador implies a certain diplomacy, if you will. The charge for the apostolic believer is just like that of a diplomat: gentleness, cajoling, giving up a comfort zone for life on strange turf, adaptable–in other words, being all things to all so that some might be saved.
