Yesterday in my church we remembered in the gospel how we must forgive 'seventy times seven'(Luke 17).This forgiveness, according to the gospel, is conditional upon the wrong doer repenting. I have always followed the belief that forgiveness should be unconditional. Indeed both our Lord and St Stephen asked that the sins of their persecutors would not be laid upon them-but there is no indication that they repented.
In families and everyday life we have to forgive wrongs without the overt repentance of the person causing the wrong in order to keep the peace.
What do the Fathers say? Or perhaps you have some insight or other information.
Please let me know. Thanks
