17 There should also be noted those courses of instruction by which pupils are forced to imbibe and embrace this false doctrine. Priests, religious men and women, ecclesiastical students, and faithful of all ages are forced to attend these courses. An almost endless series of lectures and discussions, lasting for weeks and months, so weaken and benumb the strength of mind and will that by a kind of psychic coercion an assent is extracted which contains almost no human element, an assent which is not freely asked for as should be the case.
