Former Deputy President Rigathi Gachagua has alleged a scheme by the state to use chiefs to monitor sermons in churches across the country.
Gachagua, a former administrator, claimed that chiefs and their assistants are being instructed, by people he did not mention, to keep a watch on the contents of sermons by the clergy.
The ex-DP alleged that the state has deployed the members of the administration unit to churches every weekend to intimidate bishops and preachers.
He warned that the move is retrogressive and goes against the constitution that guarantees Kenyans their freedom of speech and worship.
"I have heard that chiefs are being sent to churches to see what bishops are preaching, please chiefs that is not your work, don't be misused,'' Gachagua said.
"If you want to come to church, come and listen to the sermons so that you can be saved and join the church. Let us allow the church of Christ and let us respect the freedom of worship.''
The former DP spoke when he attended a church service in Kajiado on Sunday, a week after claims emerged there was a plot to block him from a church service in Nairobi.
Director of Criminal Investigations Mohamed Amin, earlier in the week, denied the reports saying the DCI unit operates within the parameters established by the rule of law.
Amin said they have consistently affirmed their commitment to refraining from interference in the liberties of individuals and institutions.
The DCI boss said they respect the autonomy of religious institutions.
Gachagua was this Sunday accompanied by a host of his allies who defended the church from attacks by a section of politicians.
The former DP said that the men of God are guided by the Holy Spirit and are well-educated in the Word to know what they are preaching to the faithful.
" Let us respect the freedom of worship and freedom of speech in our places of worship. Let us allow the church to spread the gospel without intimidation and undue interference from any quarter,'' he said.
"The churches must be allowed to regulate themselves. The rest of us should come and listen to the sermon, enjoy praise and worship give our offerings and go home."
The former DP said any interference with the church would not be accepted at all as it would curtail fundamental freedoms.
"These men of God know how to read the Bible and interpret it differently on how God has shown them,'' he said.
