He added that there had been no official communication with the priest’s kidnappers.
Juma’s abduction is the latest in a series of kidnappings in Nigeria that appear to target Christians, including priests.
The West African nation has faced rising insecurity since 2009, when the Boko Haram insurgency began with the aim of turning the country into an Islamic state.
Since then, Boko Haram, one of largest Islamist groups in Africa, has orchestrated attacks on various targets, including religious and political groups as well as civilians.
Insecurity has been heightened further by the actions of predominantly Muslim Fulani herdsmen, also known as the Fulani Militia, who have clashed frequently with Christian farmers over grazing land.
Nigeria’s Catholic bishops have called repeatedly on the government to restore security.
In February, members of the Catholic Bishops’ Conference of Nigeria said: “Insecurity, clearly evident in widespread loss of lives and property, has left the impression that the country’s leaders are either unable — or worse still, unwilling — to take up the responsibilities of their office.”
They appealed for “a formal meeting of statesmen and women across the board for us to think through the challenges that seem poised to push us into the abyss.”
