Abstract
The Church Fathers emphasise the importance of the fifth prayer among the petitions of the Lord's Prayer, as it is the only prayer that requires the praying person to do something in order to be heard. The paper follows the Latin Patristic tradition from Tertullian through Cyprian, Ambrose, Chromatius, and Jerome to Augustine that sets the new ground for the future Latin tradition of understanding this petition.
Chief Patristic authors put the Lord's Prayer in the context of baptism, as it is a prayer of baptised Christians. This is especially true for the prayer for forgiveness of one's sins that they received in their baptism and that has to be renewed every day.
