Likewise the commission acknowledged that "certain civil authorities made attempts" to force Eastern Catholics to return to the Orthodox Church used "unacceptable means". The missionary outlook and proselytism that accompanied the Unia was judged incompatible with the rediscovery by the Catholic and Orthodox Churches of each other as Sister Churches. Thus the commission concluded that the "missionary apostolate, ... which has been called 'uniatism', can no longer be accepted either as a method to be followed or as a model of the unity our Churches are seeking."
