Adebiyi, who was born in 1943, died in the early hours of Friday.
He served as Bishop of the Diocese from 1999 to 2013, when he retired.
On Friday morning, his successor, Bishop Olusola Odedeji, confirmed his death in a statement to members of the Diocese.
"Good morning, brothers and sisters," he wrote. It is both sad and devastating to report that our patriarch and hero, Papa Peter Awelewa Adebiyi, was called home a few hours ago.
"May his hardworking and compassionate soul rest in peace." "May God soothe all of us."
