The ministry of ushers is the oldest lay ministry in the Catholic Church. The ushers of today have descended from a long line of people of God who have gone before them. We see their antecedents in 1 Chronicles where they are called the “gatekeepers.”
During the time of Christ, the temple guard numbered in the hundreds and were the forerunners of today's ushers. The more immediate predecessor of today's usher can be found in the clerical order of porter, instituted in the 3rd Century A.D. During those times, it was the duty of the porters or ushers to guard the door of the church against any intruders who might disturb the service. The porter duties were so important that they came to be included in the rite of ordination, where they were specified as: "to ring the bells, open the church and sacristy, to open the book for the preacher."
In 1972, Saint Pope Paul VI abolished the order of porter and this important task was given over to the laity. While today's ushers don't ring bells or open the church, their primary duties and responsibilities include greeting and welcoming parishioners as they enter the church, helping them to find seats, taking up the collection, and wishing everyone a good week at the conclusion of Holy Mass.
People experience the presence of Jesus Christ in the world through the ministry of the Church. The first task of the parish community is to reach out to all people in Christian love and service. Christian hospitality draws people together, opens them to participation, and sets the tone for the liturgy.
