Lluïsa considers this quite seriously.
Erastil is the god of countryside farmers, whose priests do weddings. Lluïsa is a city dweller with wizardry; this is a god distant from her concerns.
On the other hand, Erastil was still somehow the god of countryside farmers whose priests did weddings during the time when this was illegal heresy. If nothing else, he's a formidable god.
"The Establishment of that late unlamented Hellish Church," she says slowly, "was assuredly a Diabolical work, yet even under its odious Yoke, the faith of Erastil was never snuffed entire, but sprouted irrepressibly among the People. Though I dwell in this City, and my prayers turn to the Inheritor," true as of this morning, "it seems to me that though Iomedae liberates, Erastil preserves."
Maybe someone who knows Good theology can interpret this musing as a useful theological point. On to the more comfortable ground of law! She's hit the books hard in the run-up to the convention, and consults her notes briefly.
"In making an Establishment, several Factors weigh; the enumeration of the Sanctioned Churches, and the privileges guaranteed thereunto, in like but reverse manner the enumeration of the Proscribed Churches, and the rights denied thereunto, and lastly those rights and privileges belonging to those Churches which are neither; in addition to which it may behoove to fix a single Church in primacy for Ceremonial and Juridical usage. That loathsome Hellish Establishment now past, amounting to the Tyranny of a single Vile Faith, proscribing all not subordinated to it, or in the case of Pharasma superior to it, need be no Model for a Virtuous Establishment; in older law, the church of holy Aroden was fixed in primacy and held certain special privileges; an Established Church in the truest sense, but no Tyrant Faith that, e.g., an itinerant of Desna would fear."
