Voted for To grow in selflessness and to love your spouse and his/her family as your own which then becomes the stepping stone to love everyone else..
I would place the above as the chief aim and "Fellowship, companionship, mutual help and comfort" as the secondary aim.
I am of the view that when you consider "To grow in selflessness and to love your spouse and his/her family as your own which then becomes the stepping stone to love everyone else." as the chief aim, the secondary aim of "Fellowship, companionship, mutual help and comfort" is automatically taken care of.
