St. Vincent the Paul parish Egeoja is an island parish. The parish is made up of one outstation, St. Brendan catholic church, Allah/Omagwa. They speak Igala as their linguafranca. This is because of their closeness to Kogi state that speaks Igala.
Before the coming of Christianity, the people of that area were predominantly African traditionalists(as was the case in most Igbo land). In 1936, Rev. Fr. Joseph Delancy who lived in Aguleri came to Nzam and later to Odeh, Igbokenyi, Igbedor, Odekpe and finally to Allah/Omagwa. Not withstanding the unfriendly atmosphere, Rev. Frs.Delancy, Seeny, Kettle, Vincent and Brendan went about reacting school buildings which served as school and churches especially on Sundays. The early covers of this areas suffered mickey and rejection from families and friends.
Rev. Fr. William Obeleagu who was the first visiting black priest, fought greatly against nudity and immorality.
After the civil war a parish was created in Nzam because of the inflow of Igbo speaking people who were mainly Christians and who greatly influenced the people of that area. Fr. Hillary Anisiobi was made the first parish priest and together with other priests visited Odekpe and Allah/Omagwa.
The rapid growth of Catholicism among the people let to the formation of Olumbanasaa indigenous Catholic Association with late Chief Anthony Adigwe from Odeh as Chairman and later chief Francis Agbata from Igbedor as the secretary The principal aim and objective of this association was the creation of Olumbanasaa Parish. During the tenure of Rev. Fr. Paul Emeka Ekwealor as the Parish Priest of Nzam parish with Simon Odogwu Ocha from Odekpe village and Gabriel Aborah as president and secretary of Olumbanasaa indigenous Catholic Association respectively, the Constitution of the association was made available to Rev Fr. Paul Ekwealor. After going through the constitution, Fr Ekwealor advocated that St.Mary’s Nzam was too large for only one person to her effectively coupled with the terrain of the area.
In January 1998, Holy Trinity Parish Ege-oja( Olumbanasaa) was created with Rev. Fr. Cryil Ezeh(Akpunku) as the pioneer parish priest by His grace Rev. Dr. Albert Obiefuna. He( fr. Cyril) with his explanation social type of life attracted many to Christianity and made many converts. He also introduced Udama mass( This is the practice of attending mass as a parish in one station rotationally). Above all all Fr. Cyril saw to the surveying of the parish land especially in Igbedor.
Fr. Cyril was succeeded by Fr. Ignatius Okeke( fr. Ichie Ohabuike) who introduced another method of evangelization called Inculturation.
Rev. Fr. Augustine Anyanwu took over from Fr. Ignatius. He did his pastoral work in his own way by mobilizing the Catholic to brotherly love and interstational relationship.
Rev. Fr. Gabriel Ezeanya succeeded Fr. Anyanwu. He can be best described as the messiah of the parish as he was the one who renovated the fathers house and replaced the damaged wooden boats. The climax of his achievement in Egeoja parish was the building of the modern church in igbedor within a year and five months.
