"I tell you solemnly, whatever you bind on earth will be bound in heaven..."
We are disciples of Christ. We have committed ourselves to following Him, in order that we may become the person the Father created us to be and that we may share in the eternal banquet that the Father has for us. Oh, and we're supposed to share this with others on the journey. In short, we need to evangelize and catechize.
Neither should be treated as a hobby, but rather as a vocation, one's call to a life in God. And when we truly carry out our work, it will be blessed, as promised by Christ.
What we need to watch out for is letting pride and arrogance creep into our work. We are not better than those we evangelize or catechize. We are not spiritual Know-it-Alls or the blessed Mr. Fixit. If our pride overcomes us, we become the worst caricatures of evangelization and catechesis. Instead, we are humble vessels, allowing ourselves to be filled with the Lord and letting it flow over to others. Humility for the Lord is you second and everyone else first.
But if we don't succumb, if we truly are the compassionate, humble messenger, our work becomes Christ's work and is thus sacred and blessed.
Perhaps today is a good day to spend some time reflecting your own call in the missionary Church.
