He asked the leaders to avoid any expressions on intolerance, hatred or ethnicity.
The bishop said the late Mzee Kibaki always put the nation before personal ambitions.
This, he said, was demonstrated when he agreed to a power-sharing deal with Opposition leader Raila Odinga when the country was on the brink of collapse after the disputed 2007 general elections.
“He will be remembered for reaching out to Hon Raila Odinga in 2008 in an earlier handshake that stopped the post-election violence.”
The bishops said the late president consulted widely with the church on matters of national importance and was a man who listened more than he spoke.
They said he was humble enough to agree to the voice of reason. “Where he disagreed, it was with respect and honour.”
The bishops said so selfless was the late president that he never named any road or public institution after himself.
“Mwai Kibaki believed in the war on corruption. When he came on as president, everyone took on the war on corruption,” they said.
“He was an icon of intolerance and allowed everyone to say what they wanted to say and we all remember him saying utaongea na utalala.”
