Ethics is an inherent feature of a well cultured and civilised society. It develops the mind to distinguish between good or bad behaviour, character and practices running around our society, country or the world at large. Religious ethics is vital for the proper functioning of the economic, political and social network and, therefore, for the wellbeing and development of the potential of every Nigerian citizen. This goes to mean that, the extent to which Nigeria nurtures religious principles such as integrity, self-discipline, tolerance, patience in its citizens beginning from the smallest unit of the society – the home – will determine the extent of its socio-political and economic growth. The socio-economic and political backwardness of Nigeria today is an indication for a lack of instilled ethics and moral standards in the citizens. This paper examined religious ethical values as a sine qua non for a developed Nigerian nation. The paper employed the use of comparative and analytical methods. Both primary and secondary sources of data were used. The findings are that, religious values are important for the growth of Nigeria. It is also established that the dissemination and adoption of shared ethical and moral values is essential in order to take advantage of the enormous opportunities that will lead to the growth and sustainability of the Nigerian nation.
