Jesus never called Joseph, His father, never.
How do you possibly know this? Do you honestly think the only words Jesus ever said to St Joe are the two sentences in Luke Ch 2?
I can understand if Christians still want to call their earthly father 'father' , although I don't condone it,
So what word would you have them use?
I'm not the one who is interpreting them. I simply believe them.
Until you get over this, you'll never understand where you are going wrong. Words don't mean
anything until you interpret them. To say I believe the words but I'm not interpreting them is meaningless.
A child would take the same meaning from them that I do.
Maybe, maybe not. Either way it's still an interpretation, and not necessarly the correct one.
