Is there anyone here who knows this priest well enough to provide evidence of his actions, rather than relying solely on a news article or internet hearsay?
It is a grave matter to publicly condemn a member of the clergy, and we must be reminded of the principles that govern our conduct as Catholics. The Church teaches that the reputation of one’s neighbor is a precious good, and this is especially true regarding those who hold the priestly office. To speak ill of a priest in public forums constitutes the sin of detraction if the information is revealed without a just cause, or calumny if the information is false or exaggerated.
I would not engage in such slandering for a Novus Ordo priest, nor for any lay person, let alone a traditional priest. We are bound by the law of charity toward all, regardless of their position or affiliation.
Even if a priest is found to be acting imprudently, the laity are not authorized to act as his judge or to publicly destroy his reputation. The Church is a hierarchical society, and the correction of the clergy belongs to their ecclesiastical superiors, not to the general public.
Furthermore, we must distinguish between the mere possession of an object and the commission of a sin. While the Church has long condemned the practice of astrology as a form of superstition that encroaches upon the sovereignty of God, assuming that the possession of a book equates to the practice of magic is a rash judgment.
To "disown" a priest or to treat his ministry as void because of personal suspicion is a grave error that harms the unity of the Church.
If there is a legitimate concern regarding the conduct of a priest, the proper course of action is not public denunciation, but private, fraternal correction. Let us be careful not to fall into the trap of public scandal, which serves only to weaken the faith of the simple and sow discord within the Mystical Body of Christ.
