You do that. Until then I don't believe you.
This one has a poor record when it come to veracity. Even if they could produce the claimed cite it would prove nothing except some incompetent censor or one eager to make a buck got the booklet approved to be published.
It is not church doctrine, nothwithstanding the Nihil Obstat, which only provides “Initial Superficial Assurances” to the faithful. Yet this one salivates like the Pavlovian dog claiming to have made a discovery of sorts. Publishers in past times were able to get other such material past the censors.
This one thinking it is revealing only exposes their ignorance of how the the Bride of Christ functions. They better be more informed of how the justice of Jesus works. Oh that’s right the Sin Of Presumption is their Prideful reply now but what will it be at the day of judgment?.
