If Henry (Edward or Elizabeth) had decided - for whatever reason - to "go Arian" - what would be the international repercusions of that?
Would England become a pariah nation? Would it still be perceived as Christian, considering that all other denominations are Trinitarian and intolerant?
IIRC in OTL Unitarians were tolerated (only?) in the PLC (for a time), Transylvania and Holland.
I suppose a future union with Scotland becomes somewhat problematic ...
If already discussed - please direct me to that thread.
