Moving from west to east wasn't the norm, but not unheard of. East German data show that in 1955 270,115 emigrated from East Germany to West with only 77,928 immigrating into east Germany from west.
More interesting would be that a Lutheran minister did this. East Germany went from being merely the Soviet "sector" of Germany to being it's own "Republic" in 1949, so by '55 moving eastward would have been something more than, say, moving from one county or state to another; it would have required formal "immigration" and government approval.... at a time when government oppression against anything religious was reaching it's peak.
The 1949 DDR constitution officially permitted "freedom of religion". But that was on paper only. As a matter of "policy", the 1952 party congress switched from a position of 'neutrality' on religion to active repression, a position that wasn't relaxed until 1968.
So I find it somewhat unusual that in 1955 a
minister would have been permitted immigration into the DDR.
