[2] With the Lord's inspiration and on the advice of his maternal uncle Padre Leles de Souza, Moreno decided to become a priest and join the Jesuit order.
He acknowledged later that he had not even heard of the Jesuits in his youth, but his maternal uncle Padre Leles, a diocesan priest and an acclaimed music conductor was impressed with the religious Order.
Dor Mhoineachi Rotti, a Konkani monthly magazine started in 1915 in Karachi, British India by Padre Vincent Lobo and dedicated to spread the devotion of the Sacred Heart of Jesus,[6] was shifted to Bombay around 1960.
In 1964, de Souza was given charge of it and he moved into the old Jesuit 'Professed house' in the then almost deserted and desolate Velha Goa in 1964.
It led to problems in the mail services, as letters were being returned, as the postal officials did not realise it referred to Velha Goa in English.
He was a member of the Povitr Pustokachea Vavrachi Somiti (PPVS),[12] which was a committee formed by the Archdiocese of Goa e Damão, for the translation of the bible.
Despite loving his mother tongue Konkani, and not being afraid and ashamed to speak and write in it, father Moreno was a linguist and knew around 10 languages.
He learned Latin, Portuguese, Tamil, French, Greek, English, Castilian, Catalan, Marathi, Hindi et cetera besides knowing his mother tongue Konkani.
