OK that was going to be my next question But let me make sure I understand your answer let s imagine the above scenario but without the second marriage So imagine that the two or three years say since Harry s hypothetical Jewish wife died he gradually stopped going to synogogue Indeed he now goes to church to friends weddings etc more often than he goes to synogogue but he never has formally made any profession of reconversion Now his father brother and grandmother all die tragically and Harry ought genealogically to be king If he is willing to take the accession oath that he is a faithful Protestant does he indeed become king
