You know, I have NO problem criticizing if someone (especially a Church leader) does something against the Faith. Could you show me exactly where the Church condemns what this priest is doing?
I’ll admit, after reading the OP, something seems a bit off, but I can’t put my finger on it.
Sure. Let me point you to this relevant section of the Catholic Encycopedia (http://www.newadvent.org/cathen/14221a.htm), in the article “Spiritism”, under the section “Action of the Church”:
The Congregation of the Inquisition, 25 June, 1840, decreed:
Where all error, sorcery, and invocation of the demon, implicit or explicit, is excluded, the mere use of physical means which are otherwise lawful, is not morally forbidden, provided it does not aim at unlawful or evil results. But the application of purely physical principles and means to things or effects that are really supernatural, in order to explain these on physical grounds, is nothing else than unlawful and heretical deception.
This decision was reiterated on 28 July, 1847, and a further decree was issued on 30 July, 1856, which, after mentioning discourses about religion, evocation of departed spirits and “other superstitious practices” of Spiritism, exhorts the bishops to put forth every effort for the suppression of these abuses “in order that the flock of the Lord may be protected against the enemy, the deposit of faith safeguarded, and the faithful preserved from moral corruption”. The Second Plenary Council of Baltimore (1866), while making due allowance for fraudulent practice in Spiritism, declares that some at least of the manifestations are to be ascribed to Satanic intervention, and warns the faithful against lending any support to Spiritism or even, out of curiosity, attending séances (Decreta, nn. 33-41). The council points out, in particular, the anti-Christian character of Spiritistic teachings concerning religion, and characterizes them as an attempt to revive paganism and magic. A decree of the Holy Office, 30 March, 1898, condemns Spiritistic practices, even though intercourse with the demon be excluded and communication sought with good spirits only. In all these documents the distinction is clearly drawn between legitimate scientific investigation and superstitious abuses. What the Church condemns in Spiritism is superstition with its evil consequences for religion and morality.
