Assuming that Frère Sulpice has gone through the document of Triamore p.34f, he will address Remi about the following issues at once:
There are two exclusions in the charter, which no Christian in his right mind would ever accept:
"... shall honor and defend the Tribunal and the Order in all affairs and above all other matters." is setting up Tribunal and Order as idols, and thereby voiding the charter.
"... and that he owes no allegiance nor fealty to any other Covenant or other body such as shall contravene his good oath to this Covenant, ..." is made most unclear by "or other body". Every Christian owes allegiance to the Church - which is by no means a Covenant in the sense of the Code of Hermes.
Both phrases likely do not say what the authors mean, and can be easily amended to e. g. "... shall honor and defend the Tribunal and the Order in all affairs." and "... and that he owes no allegiance nor fealty to any other Covenant or similar body such as shall contravene his good oath to this Covenant, ...".
It also might make sense to list after the signatures also the allegiances of the signataries, like priest and little friar, so as to make sure these do not contradict the charter and have not been hidden to the other signataries.
