He often said thathe would leave it to his successors to organize it. He gave greatimpetus to all kinds of activities. Mission stations were startedafresh and existing ones were given resident priests and for thispur- pose he received priests from Travancore and Cochin regions.He himself visited them frequently baptizing catechu- mensand administering Confirmation personally. Syrian Catholics fromTravancore began to come to Malabar mostly at this time. He helpedthem in their spiritual needs, visiting them on foot, as there wereno roads, and during these visits he did not heed the hardshipsand fatigue. The great educationist that he was, he involved in theopening of many Elemen- tary Schools in the diocese. He alsopurchased the bungalow and land at Malaparamba and shiftedthe Bishop’s House to the present place in 1945.

Rt Rev. Dr Aldo Maria PatroniS.J, the third Bishopof Calicut was appointed on March 28, 1948 andconsecrated on June 27, 1948. He had beenthe Superior Regular of the Mission before hisnomination and so, knew the people and the placevery well. Immediately after his consecration hebegan to organize the diocese. The period of 32years of his Episcopate is considered as the goldenera of the diocese. Bishop Patroni has contributeda lot to Malabar in the areas of education, culture and social service.He was always in the forefront to assimi- late the new perspectivesin the Church and to put them into practice. He attended the II VaticanCouncil. Bishop Patroni took the initiative to translate 18 Liturgicalbooks into Malayalam for the use of 11 Latin dioceses. It was HisLordship who arranged for the financial assistance to publish thecomplete Bible in Malayalam headed by B.L.M. His service to theSyrian immigrants in Malabar is never to be forgotten. Bishop Patroniappointed Fr C.K. Mattam as the Episcopal Vicar of the immigrants.In 1952 when Fr Joseph EdamaramS.J. was appointed the VicarGeneral of the diocese he was given the special charge of the Syrianimmigrants. When the number of the immigrants reached about alakh, Bishop Patroni requested to the Holy See for a separate diocesefor the Syro-Malabar Christians in Malabar and he discussed thematter with Cardinal Tisserant when he visited Calicut. Thus BishopPatroni prepared the way for the erection of a separate Ecclesiasticalunit for the Catholics who had migrated into the territory of theCalicut diocese. This was finally done when the new diocese ofTellicherry was erected on December 31, 1953. In the same yearBishop Patroni handed over 30 parish Churches along with theChapels, Lower Primary, Upper Primary and High Schools of thoseparishes, to the diocese of Tellicherry. After serving the diocese for32 long years, Bishop Patroni resigned from office in 1980. Then hemoved to Nirmala Bhavan, Marikunnu. During those days his mainwork was translating liturgical books into Malayalam. On his 85thbirthday on September 22,1988 Bishop Patroni left this world toreceive his eternal reward.
