1faith
noun \ˈfāth\plural faiths
b (1) : fidelity to one's promises (2) : sincerity of intentionsSo him trying to get you to say you have faith, is him trying to get you to say you have religion, its pretty typical. So you could shut him up by simply saying "I have faith in my family that they will ensure my body will be taken care of once I die" That in no way implies that you believe in imaginary people in the sky, just means that your family will take care of your affairs once you are dead.
