text: Roman Catholic sticking point seems to be that "Infallibility" thing! So what if previous Popes and customs did not ordain women? Is there ever room to grow in knowledge and change practices? 
  Certainly this custom will remain a great stumbling block to any "unity" with someone like Lutheran Archbishop Antje Jackelen. She is not only a priest, but head of the Lutheran branch. 
  
  maybe any "unity" will involve just recognizing the validity of other Christian groups having different norms. And saying "that's OK".
