My comment which included the question wasn't short. I was interested in your process. At Christian funerals, regardless of how much you know the person, there's so much behind the scenes stuff that no-one knows about. That is, until it's their 'turn' to deal with it.My homilies are usually quite short, especially if they are not churchy people or I don’t know them. So, 5 minutes or less. A regular well known parishioner would be longer but still within 10 minutes.
They will be based on the Bible reading/s chosen and tying that in with the person and the situation.
The readings are where I differ from many clergy. There are a number of ‘standards’ rolled out as the readings. (In my father’s house there are many rooms / Come to me all you who are heavy laden / There is a season for everything - a time to live and a time to die). I use them rarely. Sometimes families come with one of those already chosen because they’ve heard it at many funerals. That’s fine. Sometimes one of those fit the situation and the person perfectly and that’s fine too. But I like to get the family to share stories with me and then we choose something together that matches the person - so I’ve done some really unusual texts. I’ve used bible fishing stories many times, and farming stories (I’m in a rural area). The important thing is that the family can see some relationship between their loved one and the Scripture. Then I have to work the homily around that.
My homilies are always prepared - and then changed “on the fly” depending on what’s happening at the time.
To be honest, if the funeral has gone longer than expected, I will still give most of my homily (if not all). If they’ve asked for a Christian funeral I would be short changing them if I didn’t offer the Christian belief that this isn’t the end.
Sorry for the missive.
