Onaiyekan handed down the adviceÂ on TuesdayÂ during a sermon for the burial of two catholic priests: Rev Frs. Felix Tyolaha and Joseph Gor, at Ayati, a small agrarian hilly village on the outskirts of Ikpayongo in Gwer East local Government Council of Venue State.
He said the killings across the country must stop and called on well meaning Nigerians to unite in fighting the great evil that had befallen the country.
The cleric warned: â€œThis must not be politicised. The nation is in a state of emergency. We demand for synergy; division, especially on tribal lines will only throw our nation to anarchy.â€
He called on the federal government to act decisively to end the spate of killings across the country.
The cardinal called on the people to be vigilant and be their brotherâ€™s keeper.
He warned that if murderers were allowed to continue killing without checkmating them, it will come to a time when people will begin to use other means of self defence.
Onaiyekan called for forgiveness and warned against reprisals, adding that the souls of the righteous are in the hands of God.
He appealed for calm and advised the Christian faithful to show appreciation to God in all situations.
â€œThis is our hope which is based on our trust in God,â€ the cardinal said.
He described the death of the priests and the others as a â€œhorrific massacre which will not be forgotten for a long timeâ€.
The cardinal said the killed priests and their worshippers were martyrs of the church.
Earlier, the Bishop of Makurdi Diocese, Most Rev. Wilfred Anagbe, said the decision to bury the victims of Saint Ignatius Parish, Mbalom at the â€˜Se Sugh Maria Pilgrimage Centre, Ayati, was to honour them as martyrs of the church.
He said the barbaric acts perpetrated against the victims would attract the wrath of God and lamented the act of desecrating the church of God.
â€œIf our places of worship are no longer safe, then where can we run to in this country?â€ Anagbe asked.
He expressed optimism that their blood would restore peace and end the killings in the state and across the country.
Sympathisers, mostly Catholics, dressed in their societal attires besieged the Ayati prayer ground as early asÂ 7a.mÂ to secure seats for the historic event.
Security around the burial site was tight as only identified dignitaries apart from the clergy, were allowed entry.
