The Angeline sect is a heresy of the Ursuline church.
In-Game Description Edit
Angelines live very different lives from their Ursuline counterparts. Whereas the Ursulines emphasize the monastic lifestyle and the primacy of the Church, Angelines more strongly emphasize cohabitation with the secular world.
The Angelines effectively have the same features as their Ursuline counterparts. The only key difference, as their description suggests, is that Angeline's are not allowed to retire to a monastery.
