The Guild of St. Stephen is an international organisation of altar servers founded in England in 1904 by Father Hamilton McDonald when he formed a society of Altars Servers at the Convent of the Sacred Heart in London. In 1905, St. Pius X, Pope gave his approbation to the canonical establishment of the guild at Westminster Cathedral and in 1906, the Sacred Congregation of Rites made the guild an Archconfraternity prima primaria, enabling all the parish branches to be linked with it. The guild spread and, in 1934, Pope Pius XI enabled all guilds of altar servers throughout the British Commonwealth to be affiliated with the Archconfraternity at Westminster.
The objects of the Guild of Saint Stephen are:
To encourage, positively and practically, the highest standards of serving at the Church's liturgy and so contribute to the whole community's participation in a more fruitful worship of God.
To provide altar servers with a greater understanding of what they are doing so that they may serve with increasing reverence and prayerfulness and thereby be led to a deepening response to their vocation in life.
To unite servers of different parishes and dioceses for their mutual support and encouragement.
Membership of the Guild is open to any server, without limit of age, who can serve Mass, and who has shown a wish to live up to the objects and standards of the Guild. Servers will have been given adequate training and reaches the necessary standard before being admitted to the sanctuary and then should serve satisfactorily for a minimum of six months before being enrolled as a member of the Guild. The parish priest, or the local director of the Guild, decides whether a candidate is eligible and worthy of admission to the Guild and he is empowered to perform the ceremony of enrolment and invest the server with the Guild medal, using the prescribed form of enrolment.
