The name Ruhalaya is the combination of the Syriac word Ruha (Holy Spirit) and the Sanskrit word Laya (house, abode), meaning Abode of the Holy Spirit, placing the seminary rightly in its proper ecclesial and cultural milieu. In this House of the Holy Spirit, the future priests and missionaries are enlightened, equipped, and formed for the missionary apostolate.Ruhalaya imparts formation to priesthood, with special emphasis on the human, spiritual, intellectual and missionary training, firmly rooted in the ecclesial traditions of the Syro-Malabar Church and fully adapted to the missionary context of India. Although Ruhalaya is primarily intended for the priestly formation of the future missionaries of MST, it is open to the students of all Syro-Malabar mission dioceses. In exceptional cases students of other sui juris Churches may also be admitted.
In the past 30 years 1290 students completed their philosophy and 333 students completed their theology studies here. At present, Ruhalaya has 16 members on the staff and 123 resident students in philosophy and 62 resident students and 2 day scholars in theology.
