Why would Boniface, who dedicated his life to conquering paganism, help Bill Wilson write a book that allows one to pick a god/higher power of one's choosing? Wouldn't Boniface have insisted on the Catholic God, given his history? How do you square this?
Boniface returned to Upper Hessia and repaired the losses which occurred during his absence, many having drifted back into paganism; he also administered everywhere the Sacrament of Confirmation. He continued his work in Lower Hessia. To show the heathens how utterly powerless were the gods in whom they placed their confidence, Boniface felled the oak sacred to the thunder-god Thor, at Geismar, near Fritzlar. He had a chapel built out of the wood and dedicated it to the prince of the Apostles. The heathens were astonished that no thunderbolt from the hand of Thor destroyed the offender, and many were converted. The fall of this oak marked the fall of heathenism. Tradition tells us that Boniface now passed on to the River Werra and there erected a Church of St. Vitus, around which sprang up a town which to the present day bears the name of Wannfried. At Eschwege he is said to have destroyed the statue of the idol Stuffo. Thence he went into Thuringia.
The difficulties that confronted him here were very great Christianity had indeed made great progress, but it had become mixed up with heretical tenets and pagan customs. This was due to a great extent to some Celtic missionaries, several of whom had never been ordained, while others had been raised to the priesthood by non-Catholic bishops, though all performed priestly functions. These taught doctrines and made use of ceremonies at variance with the teaching and use of the Roman Church, especially in regard to the celebration of Easter, the conferring of baptism, celibacy, the papal and episcopal authority. Besides, many were wanting in education, some scarcely able to read or write, and equally ready to hold services for the Christians and to offer sacrifices to the idols for the heathens. A neighbouring bishop (probably of Cologne) also gave trouble, by laying claim to a part of the district under Boniface's jurisdiction and treating his authority as an intrusion, thereby indirectly strengthening the party of the heretics. All this caused him great anxiety and suffering as may be seen from his letters to England. He overcame all, thanks to his episcopal dignity and to his own personality, full of courage and zeal in the cause which he defended, and supported by the authority of the pope and of Charles Martel.
