This Sunday's gospel for the 15th Sunday in Ordinary Time tells us of Jesus sending out the apostles to preach and his "marching orders" to them - including some details about uniforms!The first reading gives us Amos, a simple man the Lord had called to be a prophet, who does such a good job that he's banished from the place where he prophesied!
The second reading, from Ephesians, includes a great description of how blessed we are to be the people of God.
