maber43:
My question is, what’s the Church true teaching on nudism or naturism? We’re have asked our Pastor about this and he said
as long as your intention of doing this is pure not to sin. Is he right?
Thanks and God blessings,

I think your priest must have forgotten a few things. Perhaps he needs to read up on the Virtues of Chastity and Modesty .
Chastity and Modesty
The virtue of modesty, in general, may be described as that virtue which prompts us to be decorous, proper, and reserved, in the way we dress, stand, walk, sit—in general in the way we behave exteriorly. This virtue of modesty bears a relation to other virtues besides that of chastity, especially to the virtue of humility. In a special manner, however, the virtue of modesty is particularly regarded as the guardian of chastity in thought, word, and action.
St. Thomas says that it is the virtue by which we rightly regulate our conduct in respect to those things that can lead to impure thoughts, desires, and actions, in ourselves and in others. He says that, while chastity deals with the regulation of difficult things, powerful passions and strong desires for pleasure, modesty deals with the regulation of easy things, the remote and proximate occasions and conditions that lead to unholy desires. Thus we see that modesty is a virtue allied to the virtue of temperance, or the general habit of self-restraint.
It is this virtue of modesty, in its relation to chastity, which prompted the Holy Father to address himself to the Bishops of the world, through the Sacred Congregation of the Council, and to remind them that “it is altogether imperative to admonish and exhort, in whatever ways seem most apt, people of all stations, but particularly youth, to avoid the dangers of this kind of vice which is so directly opposed and potentially so hazardous to Christian and civic virtue. ‘How beautiful then is modesty and what a gem among virtues it is!’ Therefore, let it not be offended or violated by the easy allurements and attractions of vices which arise from that manner of dressing and from other actions what we have mentioned above and which decent people can but lament.” Again, in his encyclical letter on Holy Virginity, our Holy Father writes about modesty: “Educators of the young would render a more valuable and useful service, if they would inculcate in youthful minds
the precepts of Christian modesty, which is so important for the preservation of perfect chastity, and which is truly called the prudence of chastity. For, modesty foresees threatening danger, forbids us to expose ourselves to risks, demands the avoidance of those occasions which the imprudent do not shun. It does not like impure or loose talk, it shrinks from the slightest immodesty, it carefully avoids suspect familiarity with persons of the other sex. . . . He who possesses the treasure of Christian modesty abominates every sin of impurity and instantly flees whenever he is tempted by its seductions.”
