The name Ruhalaya is the combination of the Syriac word Rūha (Holy Spirit) and the Sanskrit word ālaya (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 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 eparchies and arch-eparchies. Students of other sui iuris Churches are also admitted.
