If I choose to be “sprinkled”, that is not a sign of disrespect to God. I’m pretty sure God won’t need my ashes to resurrect me. He is all-powerful, after all. My sprinkles will be in places that I want my grandchildren to visit and remember me. Reading, studying, fishing...all good reasons to visit Mimi!
I would still consult your local priest, inform him of this decision and the motives, and listen to his advice.
