Machakos diocese is one of the youngest dioceses in Kenya administratively yet it prides itself as the oldest having being created in 1985. It has since been divided in Kitui Diocese (1995), Garissa Diocese (2007) and recently Makueni diocese (2013), with Machakos Diocese remaining. Initially the diocese was very huge and posed an administrative challenge. Then it was split and gave rise to the AC
K diocese of Kitui in 1995. It later was split to give rise to the diocese of Garissa in 2007. Kenya ushered in a new constitutional dispensation in 2010 which gave rise to new form of government in 2013 with two levels of government namely the 47 county governments and the National government. With this new development the ACK Machakos Diocese found itself spanning across two counties namely Machakos and Makueni Counties. It is at this point that it was decided to split the Machakos Diocese again in to two to align it with the new administrative and political boundaries. Therefore in 2013 the diocese was split into Machakos diocese and Makueni Diocese. The Right Rev Joseph Mutungi was consecrated as the new bishop of the Machakos diocese. The Machakos Diocese is geographically situated in Machakos County, Lower Eastern Region in Kenya. It is in Machakos Town 65km South East of Nairobi. The climate is semi-arid, and dependent on rain-fed agriculture. The Diocese is estimated to have 7,000 members. It has a dedicated secretariat of twelve administrative and support staff. There is also a team of 53 full-time clergy, 17 attached-clergy, six evangelists who minister in the parishes within the diocese, and five clergy seconded to other institutions. It has six Archdeaconries covering the entire Machakos County namely:
• Cathedral Archdeaconry
• Athi River Archdeaconry
• Kangundo Archdeaconry
• Yatta Archdeaconry
• Mwala Archdeaconry
• Kathiani Archdeaconry
After the split of the Machakos diocese into Makueni and Machakos diocese, many of the strong parishes became part of the new Makueni diocese. The Machakos diocese inherited fewer parishes. The challenged was even bigger given the fact that most of the clergy identified with Makueni diocese. The Diocese therefore needed to ordain more priests to serve in the parishes that were left without ordained clergy. All this required huge financial obligations for development and sustenance.
