st. thomas aquinas

Et ideo convenienter divina sapientia homini auxilia salutis confert sub quibusdam corporalibus et sensibilibus signis, quae sacramenta dicuntur.

my translation of aquinas

And therefore it is fitting that Divine wisdom gives the help of salvation to men through these various corporeal and sensual signs, which are called sacraments.

the newadvent.org translation, "literally translated by fathers of the english dominican province"

Divine wisdom, therefore, fittingly provides man with means of salvation, in the shape of corporeal and sensible signs that are called sacraments.

while i fully realize that it's my word here against the fathers of the dominican order, i've never seen auxilia used to denote anything other than an aid or help. while "means" could easily fall in this realm, "means" has an entirely different connotation with regards to salvation. i believe aquinas meant for the sacraments to be aids or helps of salvation, not vehicles, causes, or purveyors of it.
