If by churchy widower you mean someone who is good, clean living and doesn't smoke or drink , then you have my sympathy WRT to buying presents.
My dad (not a widower. still happily married) but he's 76 yo, doesn't smoke or drink and is diabetic so can't load him with chocolate.(And yes he goes to church every week, several times a week)
My dad is very outdoorsey. I'd buy him things he maybe wouldn't buy himself but would find useless and a bit luxurious.
Really good quality gloves, scarf.
My brother bought him a flipping brilliant outdoor 3-in-1 coat.
Maybe a brand new road atlas for the car (Yes dad that 2001 AA roadMap is maybe a bit out of date. Half those roads don't exsist now) 
Good quality pen,ink pen , propelling pencil set.
