Towards the end of 1927, a suspended Roman Catholic priest, Adam Anthony Oraczewski (1883‒1973) published a 60-page pamphlet in Kansas City, Missouri. It has a bold title, All in One True Faith and the front page features the author dressed in the papal white, declaring that since August 7, he was Adam II, Pope of the Holy Catholic Church.
Among the modern alternative popes, Polish-American Adam II is certainly among the least known and one of the earliest. He lived until he was 90, but we have relatively few sources to his life and even less on his papacy. However, thanks to the two booklets, a few newspaper articles, and some official records, it is possible to write a brief biography. Still, many lacunae and uncertainties remain. Therefore, any further information on Adam Anthony Oraczewski is most welcome.
