My mother insisted to scatter the ashes of my father on a campsite in a provincial park near my town, 1000 km from where she lives, claiming that this was my father's wish. My father is catholic, my mother is converted catholic (was baptist), I am catholic.

I refused to have anything to do with this and offered to pay for a grave in our local cemetery, but she refused. Now she is telephoning me to ask me to bring flowers to the camp site in the park where she scattered my father's ashes. I refused to do this because I feel that this would implicate me in her sin. Also, I find it difficult to offer a memorial to my father at a campsite. It all feels so wrong. Furthermore, she has told me that she has requested in her will that I am to scatter her ashes in the same place and that I am bound to it because it is my duty to honour her last wishes. I have told her that I will not do such a thing, regardless of whether it is in her will.

However, by not fulfilling my mother's demands (bring flowers to the camp site and to scatter her ashes there) am I breaking the commandment to honour and obey my parents? What is the correct way for me to deal with this situation without committing a sin? What will happen to my father's soul?
