Pope Francis said the mass to thousands of people in the Franso Hariri stadium packed in Erbil.
At the end of the last official event before returning to Rome Monday, Francis told the crowd: "Iraq will always stay with me, in my heart."
He closed by saying "Salam, Salam, Salam [peace, peace, peace, peace]".
Earlier, the pope led prayers to Mosul - an old fortress of an Islamic state of the terrorist group.
He flew to helicopter and was welcomed by a crowd in the decimated city of northern Iraqi, where lives a handful of Christian families.
Thousands of Christians fled the area during the occupation, where they faced the conversion, death or pay a tax for non-Muslims.
On the way to the place, he stopped by the ruins of the houses and cathedrals that had been destroyed by violence, to hold a moment of silence.
He then participated in the service of a place of the lively city, surrounded by ruins of several damaged churches, which were destroyed when they had invaded the region in 2014.
"How cruel is that this country, the cradle of civilization should have been afflicted by a stroke of barbarism, with places of old adoration destroyed and many thousands of people - Muslims, Christians , Yazidis and others - displaced by force or killed, "he told the crowd.
"Today, however, we reaffirm our belief that fraternity is more sustainable than fratricidal, this hope is more powerful than hatred, peace more power than the war."
Pope Francis added that hope could not be "silenced by blood overthrown by those who perverted the name of God to pursue paths of destruction".
In prayer, he says, "If God is the God of life - for it is - then it is wrong to kill us to kill our brothers and sisters in his name. If God is the God of peace - for So it is - then it is wrong for us to make war on its behalf.
"If God is the God of love - for it is - then it is wrong for us to hate our brothers and sisters."
He concluded the prayer saying: "For you, we entrust all those whose duration of earthly life has been cut in the violent hand of their brothers and sisters; we also pray for those who have caused injuries to their brothers. and sisters. May they repent, touched by the power of your mercy. "
A white dove was also released by Pope Francis, to symbolize peace - a current theme for its papal visit.
In 2014, in the Al-Nuri mosul mosque, Abu Bakr al Baghdadi gave a sermon in an extremely rare public appearance, where he announced the calif.
Mosul was released in July 2017 after a three-year three-year brutal terror regime, which left around 9,000 to 15,000 dead people.
The Vatican hopes that the appearance of Pope Francis in Mosul will encourage Christian communities to stay in the region, despite years of violence and persecution.
The pope visited one of the world's most influential Muslim leaders Saturday, Grand Ayatollah Ali Al Sistani, where men discussed the problems facing the country's Christian communities.
Following the meeting, Al Sistani said he wanted that Muslims and Christians coexist into Iraq and called for other religious leaders to hold great powers to account and for wisdom and the meaning of prevailing on the war.
