In this Sunday’s Gospel (Mark 9 :38-43, 45, 47-48), a “non-disciple” of Our Lord casts out devils in His name. The disciples of Jesus tried to stop him. This parallels the episode in the First Reading in which Joshua failed to understand that the prophetical spirit was essentially for the service of the whole people.
We, as a people of faith, do not have a monopoly on good works. When anyone does good, and serve the least of his brothers and sisters, he is already making God present in the world. Thus, “anyone who is not against us is for us”.
The least we can do when we come across someone who does good, is to support him, and perhaps by doing so, we will lead him to embrace the fullness of faith.
