Roe's conversion experience was unusual: he tried to convert an imprisoned Catholic to Protestantism, but found himself defeated in argument. From this time, according to
Challoner, "Mr. Roe was very uneasy in mind upon the score of religion; nor did this uneasiness cease till by reading and confessing with Catholic Priests he was thoroughly convinced of his errors and determined to embrace the ancient faith. Having found the treasure of God's truth himself, he was very desirous to impart the same to the souls of his neighbours." Consequently, in 1607 he entered the
English College at Douai to study for the priesthood. Roe was not only content to rub people up the wrong way, but to make sure that they noticed. When the Prior had some cupboards removed from near to his bed, Roe declared: "There is more trouble with a few fools than with all the wise; if you pull down, I will build up; if you destroy, I will rebuild." He was expelled from the college in 1610 due his temperament, records stating that "we consider the said Bartholomew Roe is not at all fitted for the purposes of this College on account of his contempt for the discipline and for his superiors and of his misleading certain youths living in the College and also of the great danger of his still leading others astray, and therefore we adjudge that he must be dismissed from the College." Roe did not leave quietly, but used his considerable skills to organise a campaign against the authorities. A significant body of monks seem to have seen him as some sort of hero and backed his appeal to the President. This allowed him later in 1613 to join the
English Benedictine Priory of St Laurence at
Dieulouard in Lorraine (today
Ampleforth Abbey), being ordained in 1615. There is no record of him being at all troublesome at Dieulouard. He became a founder member of the new English Benedictine Priory of St Edmund's, Paris, (today's
Douai Abbey) hence his religious name Alban of St. Edmund. Priory of St. Laurence, Dieulouard ==Ministry and arrest==
