How would I translate the word "consequendum" in this sentence?
"Summa doctrinae fidei ad salutem aeternam consequendum necessariae, quae Sacris Novi Foederis libris plene & perfecte continetur."
I'm pretty sure that "consequendum" is a future passive participle functioning as a substantive, and not a gerund or gerundive. However, since it does not modify anything, how would I translate it? Any translation seems like it would end up modifying the word "doctrinae," but this can't be the case since they don't agree.
