The role of the altar server is to assist the priest at Mass and other ceremonies. Assisting a priest saying Mass is one of the greatest honors that lay people can undertake.

At Holy Spirit, at the end of the fifth grade, boys and girls may volunteer to become servers with the approval of their parents and the pastor. Accepted as an altar server, the youths must take training and be committed to serving at Mass when assigned. In addition to training, the candidate is required to serve at least four times as an intern before becoming an altar boy or girl.

There are four steps required after being accepted into the ministry and the initial training. Beginning with step one, the new server will walk in procession and observe the roles played by the other servers. Being mentored by the eighth grade servers, the younger servers will work their way through the other steps until reaching step four when they will become full fledge altar servers. While the senior servers guide the candidates through their training, they continue observing the performance of the younger altar boys and girls on the altar serving to maintain an acceptable standard of service at Mass.
