Queen should first determine how many gods she believes in, 3 gods or 1 god.If one god then his name and if his name is not jesus(p.b.u.h)and holy ghost then what position and status do jesus(p.b.u.h) and holy ghost hold in christianity.
this is most vague and unclear oath i have ever seen.it actually questions foundation of christianity.

That is the oath of allegiance for the british armed forces. I don’t think it has much to do with how many gods the queen believes in.
