It's the first time a serving Pope has went to a church for the denomination.
During his time at Evangelical Church of Reconciliation in the city of Caserta the Pontiff asked for forgiveness for the actions of some Catholics towards Pentecostals.
Francis was told by the pastor there, Giovanni Traettino, that many Evangelical Christians pray for the Pope and thank the Holy Spirit for his election.
The Holy Father had lunch with the congregation after the service before returning to The Vatican by helicopter.
