Missionary Society of St Thomas the Apostle (MST) is a missionary institute of the Syro Malabar Church. The Purpose of the Society is mission ad gentes, in India and outside. Remaining faithful to the liturgical, theological, spiritual and disciplinary heritage of the Syro-Malabar Church, the Society takes up missionary apostolates in territories and among peoples and groups in which the Church has not yet taken root. True to its purpose the Society also helps to establish "Churches which would be adequately organized and would possess their own proper strength and maturity" (AG 6).
