Calvary - spoilers

Calvary is hardly entertainment. I found it very dark at first, with nasty people and a horrific ending. But I found I couldn't stop thinking about it, and needed to make sense of it, especially as many reviews see a comedic element in it. Well, after lots of thought and with the help of comments on the IMDB site I now have something to say.
 Brendan Gleeson is first class, playing the lead as a flawed but basically very very good priest. The word, integrity comes to mind.  Kelly Reilly is also suberb, playing his vulnerable daughter (he was married before being ordained).
The rest of the cast have more smaller, almost cameo, roles, and the characters are quite one dimensional,
I'm not going to write the story here, but it features a week in the life of Father James, who has been told he is going to be killed on the beach the following Sunday, because he is GOOD priest. He's going to be a sort of scape-goat for all the sexual crimes of Catholic priests. He keeps the appointment and is shot through the head.

As a Catholic I was interested in the parallels with the Gospel story. Right, James, an innocent man, is condemned to death. Throughout the week we see him visiting the dying,(author who wants to end it all) the imprisoned, (murderer who ate his vicitm/s) the sick (woman beaten by husband) Same woman is in to sex and drugs, the wicked, (the rich land owner more or less confesses to this) the lost (young disillusioned youth) His non-judgmental attitude seems very Christ like. This last week seems very much an agony in the garden and carrying of the cross. Oh, the church is burnt down and someone kills his dog too).
Jesus fell three times. Well, James gets drunk and in to a fight at the pub. (Good for him. His parishioners were wankers) He also bawls at his assistant priest, who is the biggest wanker of the lot. On the beach he has wounds on his hands from the fight.
There is an apocryphal story that  woman named Veronica helped Jesus while he carried his cross. There is a Veronica in the story. Her husband has been killed, but she has great faith and is like a light shining in the middle of this dark story. She must have been a consolation to James.
Part of his desolation must be that he does not seem very effective. However, the author who wanted to commit suicide seems to get over that, and has successfully completed his book, the land owner breaks down and wants to see James. (it doesn't happen as James is killed) and the disaffected youth decides to join the army. (Not sure if James would have liked this, as he was against killing. Death and killing are talked about throughout the film).
But James' death is not the end. We segue to his daughter, visiting her father's murderer in prison. It seems to me as if it's in forgiveness, although we hear no words, just see a tear. To me, this is a sort of resurrection. She is carrying on her father's work, visiting the sick, and more importantly, FORGIVING.
Apparently, the book is about the five stages of grief, but I don't know enough about that to have a view.
I've also read that all seven vices are dealt with, gluttony (the drink) sloth (the assistant priest) pride (the land owner, and maybe the surgeon) lust (the male prostitute and the wife on drugs) anger (everyone) Can't remember the other two vices.
