To be an altar server is not simply do things and to go and get things for the priest at holy Mass. After all, the priest can do those things himself. You are not there simply to help. The priest relies on his altar servers, yes, but the reason is far greater, more noble, more powerful, and more true than you might assume. In the capacity of an altar server, you are joining with the priest in leading the people of God, in the worship of God. If you understand this, you will come to see the real importance of what you are doing in a whole new light.
Who then is the altar server in this image of the divine worship? The altar server represents and reflects on earth those we call the heavenly host – that is, the saints and the angels who surround the throne of Christ in praise and worship.
At Saint John the Evangelist, anyone who has received First Holy Communion may learn to serve at Mass.
