Embarrassing Question 1: Proving that christians worship 3 not 1

In the name of Allah the Merciful

The question today is very simple Did father crucified ? if no then who crucified ? the aim from this question to prove that christians worship three Gods not one as they say 

Trinity

 it's a faith in christianity that father is God,Son is God,Holy spirit 

is God but they aren't 3 but 1 !! so the 3 are one and the one are 3 it's simply

1+1+1=1 !!

Shekh ahmad dedat had a comment on this faith you could watch it

So to prove our point of view that they worship 3 i made  a simple question  Did father crucified ? if no then who crucified

I asked this question to a bible scholar and a priest , the bible scholar didn't answer me and this is the  conversation recorded

Imaginary conversation for explaining

Muslim:Did father crucified ? if no then who crucified

Christian : No father didn't but the son crucified

Muslim:if father didn't crucified but son crucified then they aren't 

one because if they are one both will be crucified

Explaining

if father didn't crucified but son crucified then they aren't 

one because if they are one both will be crucified but you said one did other didn't so we conclude that christian worship 3 not 1

How could the priest Fool you 

Both died 

he might say father and son crucified but he fall in a large hole by   this because by church order he is hertic because bible say God couldn't die

LORD, are you not from everlasting? My God, my Holy One, you will never die. You, LORD, have appointed them to execute judgment; you, my Rock, have ordained them to punish.

Habakkuk 1:12 

so by this words he is against christianity and bible so he is wrong 

Only the body died

this also against christianty because they say that adam eat from the tree so it's unlimited sin so the only way to be sinless is something unlimited die on cross and the only unlimited thing is God so he must died , but the body isn't unlimited so the salvation won't happen if the body only died and this is against christianty 

teaching

conclusion

That christians worship 3 not one and this is against the prophet teaching that listen israel our God is one , so this tells us that christianity isn't true religion and it fall in this important test
