History has it that the Catholic Church arrived in Ijebu Ode in 1911. The faith had actually been brought from Esure by the late Chief Madasa Ignatius Washington Osilaja of Ijebu Ode. The First Church was built in 1911 and was then St. Sebastian Catholic Church and later turned to St. Sebastian Catholic cathedral at the creation of the Diocese of Ijebu Ode in 1969 by Pope Paul VI with late Most rev. Anthony Saliu Sanusi as its first Bishop followed by Most Rev (Dr) Albert Ayinde Fasina in 1990 as the second and Most Rev (Dr) Francis Adesina as the third and current Bishop of the diocese.
The Church building built in 1911 began to collapse and around the year 1948, Fr. Young started block making in preparation for the building of the existing Church. Its foundation was laid in 1950 by Bishop L.H. Taylor. The said church was at that time in history was an out- station parish of the Lagos diocese. (The Archdiocese of Lagos was not yet raised to the status of an Archdiocese). Late Rev. Fr. Joseph Adeneye laid the foundation of the present Mission (fathers’) house.
The growth of this church has greatly hinged upon the assiduous effort of the Irish fathers e.g. Fr. T. Galvin, Fr. B. MacCarthy and Ijebu early priests Frs. J. L. Sadiku, M.O. Sanusi. From Epe and Orugbo respectively and some others who were Germans and French. Fr. Young and Fr. Gunn were remarkable at the growth of the Church at its early stage, so also was Fr. Kearney. Fr. Horgan, a German and Fr. Lopton, a French man, Fr. E. Birmingham were priests whose pastoral zeal bore fruit among the people of Ijebu ode, Fr. Husse was nothing less than great tan these great missionaries, so also Fr. Haniffty.
