It’s no news that the religious institution in Nigeria is fast becoming a venture. In fact one could be right to assert that among the easiest access to quick money and wealth in Nigeria, religion is ranked topmost with peculiarity to church ministry. This is obviously evident as there is an alarming rate at which individuals push their way into church ownership and ministry. Nowadays the population of clergy in Nigerian society has heightened as new religious groups and centres or church keep springing up every now and then, in every nook and cranny in the society. Moreso is the frequent paraded massive wealth allegedly acquired by church leaders and church founders in contemporary Nigerian society. The rampant and unbridled wealth show-off and competitions of prominent church leaders and founders has transcended into a conspicuous motive thereby creating loopholes that raise questions such as; is it appropriate that a pastor or church founder to own a massive possession of wealth?, should the preaching ministry be used as means to life sustenance?, these questions been asked however stir up controversies and criticisms and suspicions leading to a check on the integrity, mistrust and lack of followership from the congregation to the church leadership. Church commercialization has impacted immensely the Nigerian society in a positive way, particularly its economic development and sustenance. However, it is unfortunately transmuting into a controversial phenomenon consequently leading to spiritual backwardness or religious confusion, social chaos and economic decline. Therefore through a qualitative method, the paper examines reasons prompting church commercialization in Nigeria, particularly the emerging “mega churches” in contemporary Nigerian society. It will explore the economic implications of such act towards Nigerian societal stability. The religious market theory will be used as framework for the paper.
