The Feast of Our Lady of Mercy is one of the activities that are most important in our Calendar of events and is celebrated once a year by the entire Catholic Church. For the first time in Kenya the feast was celebrated differently because it was merged with the international day of peace thus changing the name from Mercy Day to Mercy and Peace day 2019. The event was held on 21st September 2019 at Mukuru promotion center. It event kicked off with a clean-up exercise and a procession in a bid to sensitize the community on the importance of environmental conservation. This is in line with the sustainable development goal 13 which calls for care of environment and mother earth as a whole to curb the issues of climate change.
