We searched for "CAC Glorious Source Assembly" together with Iju-Ota and with Nigeria, and found no listing, Facebook page, news mention, map entry or denominational register entry for a congregation of that exact name in that town. The searches instead returned unrelated bodies with similar wording, such as a Christ Apostolic Church congregation in West Bromwich in England registered with the UK Charity Commission under the working name "CAC Glorious Assembly," based at Charlemont Road, West Bromwich, and other "Glorious" assemblies in Ibadan and Port Harcourt (Charity Commission register, cacgloriousassembly.com, Facebook). The parent denomination itself is well established and real, as Christ Apostolic Church is Nigeria's first Pentecostal church, formally established in 1941, and Iju is a genuine town in the Ado-Odo/Ota local government area of Ogun State (Wikipedia), so a small local assembly there is plausible. The findings are summarized here for space; the full research was weighed in the review.
Our conclusion: Christ Apostolic Church is a long-established Nigerian Pentecostal denomination that holds the historic Christian faith, and Iju in the Ado-Odo/Ota area of Ogun State is a real town, so a small assembly of this name there is entirely plausible. However, our independent search found no listing, social page, map entry or denominational record for this particular congregation, and the similar names we did find belong to other Christ Apostolic Church
We have asked this church for one piece of extra evidence: a photo, a link, its denomination, or a church that can vouch for it. The moment we can verify, this report is upgraded. Without a response, the listing is paused after 14 days.
