The new Pope is a man of "utter fidelity", the Archbishop of Liverpool told worshippers at the city's Metropolitan Cathedral.
Archbishop Kelly said the new pope was his hero
Archbishop Patrick Kelly celebrated the Mass at short notice in the cathedral to celebrate the papal election.
Cardinal Joseph Ratzinger, 78, was elected as the new head of the Roman Catholic church on Tuesday.
The German, to be known as Pope Benedict XVI, appeared on the balcony of St Peter's just after 1645 BST.
The archbishop said the new pope fitted the set Bible reading scheduled for Mass that day which said the Church's shepherds must be men, "full of the Holy Spirit and faith."
"It is obvious to me that our new pope will lead us with utter fidelity," he told the congregation.
The archbishop recalled his days as a student in Rome in the early 60s when Joseph Ratzinger was one of the leading figures in the Second Vatican Council which revolutionised the Roman Catholic Church.
"One of our great heroes was Joseph Ratzinger and nothing he has written since has deviated from the vision of that council."
The archbishop praised one of the new pope's first decisions saying: "I've already heard he will be going to Cologne in August for World Day Of Youth and obviously it will be very special for him.
"I have been rash enough to say I will be going with the youth by coach - that should be a very special occasion."
The newly-elected pope confirmed on Wednesday that he would be attending the world youth festivities from 16-21 August in Cologne - Liverpool's twin city.
