This is a link that apparently explains his views, according to this website. I’ve translated it into English from Portuguese, thanks to Google Translate. Note that it appears to be a Traditionalist Catholic site and could easily be untrue as they may have some agenda, but it appears not be be, as these words were apparently given to the site by a priest from the friary where P. Pio lived and maybe I’m a bit naive and people may chuckle reading this but I’d expect a Catholic site to tell the truth but anyway, here’s the link :

Here is the translation of the article…
One of the little known facts related to Padre Pio is his brutal and merciless hatred of heresy, in particular to Protestantism. His repugnance to the heritage of Luther was such that on one occasion blurts out, comically: "Know ye not that Protestantism also [1] has a supernatural founder? You know now, it is an angel, and his name is Lucifer. "
It should be noted, moreover, that Padre Pio lived in a convent, and had no full contact with the outside world, and his anger against Protestantism was certainly moved in some way by your misticidade. This is clear when he says: “It is the Virgin who cry because they do not fight this enemy [Protestantism].”
The stigmatized holy still makes two simple and striking analogies - Padre Pio was excellent in making comparisons - to warn against the danger of Protestantism:
"Protestantism is like a dark cloud that quickly covers the sunshine. You know, therefore, that a cloud is no grander than the sun, and it does not cover forever. The cloud passes by the sun, as well as Protestantism pass before the Church, not to cause any harm, because that does not come from heaven can never win heaven itself. "[2].
"Look at Protestantism as a large hospital, where doctors are not real doctors, and medicines have no effect because they lack the correct substance. You will see, therefore, that a dying enter this hospital begging him to heal, even hear a solution to his illness, or will be treated in a careless fashion, and death will be your sole purpose. So is Protestantism: there are pastors who are not pastors, and there are doctrines that do not save because they are not the doctrines of Christ. And their sole purpose [Protestant] is eternal death, the divine mercy does not place in opposition the fearful justice. "
Finally, the radical way in which Padre Pio was the Protestant heresy should be taken as an example for us that we are children of the Church of Christ, for, as the saint said, "it is impossible to love the Church and not fight to destroy [3] this heresy. "
