The theologians of the sixteenth and seventeenth centuries were greatly exercised by the conclusive evidence which proved that people known to be devout and professing Christians had been present at the Sabbath, joined in the ceremonies, and worshipped the witches' god. The Inquisitors recognized the fact, and devote many pages of their books to the discussion of the course to be followed in the case of Christian priests, coming finally to the conclusion that if a priest merely went to the Sabbath but was not in any way in an official position there his sacred character preserved him from evil. The theologians of the Reformed Churches, who could not accept the sanctity of the priesthood with the same ease and were also desirous of finding some means of accounting for the presence of the devout laity, boldly evolved the theory that the Devil could for his own purposes assume the shape of good Christians in order to mislead the witches. By this plea the accused often succeeded in escaping when the examiners were religious ministers, but it was of no value to them when the trial was in a court of law, and the fact of their presence at an illegal assembly was proved. Lord Coke's definition of a witch summed up the law on the subject: 'A witch is a person who hath conference with the Devil, to consult with him or to do some act', and any person proved to have had such conference was thus convicted of a capital offence and sentenced accordingly. This accounts for the fact, commented on by all students of witch-trials, that a witch was often condemned even though she had invariably used her skill for good and not for evil; for healing the sick, not for casting sickness. If it were proved that she had obtained her knowledge from the 'Devil' she had broken the law and must die. FOOTNOTES: [Footnote 1: _Journal of Hellenic Studies_, 1894, p. 160.

CONTINUITY OF THE RELIGION Of the ancient religion of pre-Christian Britain there are few written records, but it is contrary to all experience that a cult should die out and leave no trace immediately on the introduction of a new religion. The so-called conversion of Britain meant the conversion of the rulers only; the mass of the people continued to follow their ancient customs and beliefs with a veneer of Christian rites. The centuries brought a deepening of Christianity which, introduced from above, gradually penetrated downwards through one class after another. During this process the laws against the practice of certain heathen rites became more strict as Christianity grew in power, the Church tried her strength against 'witches' in high places and was victorious, and in the fifteenth century open war was declared against the last remains of heathenism in the famous Bull of Innocent VIII.
