Is this ever said in its original Qunlat?

Solas is surprisingly fluent in Qunlat too considering how much he despises the Qun. Try listening to him talking to the Viddasala on YouTube. I think he is effectively quoting back some of her own teachings to her.

You will recall that one of his Fade stories involved a Qunari baker, so it would seem that he must have been observing them from the Fade during his sleep, since I feel it is safe to assume he hadn't actually visited anywhere connected with the Qun (even in the past) during the year after he woke up before entering the Inquisition. Given his ire against the Qun and how much they "offend" him by their mere existence, I think this had to have been based on more than just vague rumours.

Mind you, I had this theory that either Solas or one of his acolytes was the original Koslun, who came up with the philosophy for a perfect society, minus any deities you will note, only for it to be twisted into what became the Qun. After all it is clear that the Chantry was the invention of Drakon and not Andraste and various Divines have probably interpreted her teachings in ways she never intended, so it wouldn't be surprising to learn that the same occurred with the teaching of Koslun. You have to admit it is understandable why he so loathes the Qun if Solas did have anything to do with Koslun, particularly considering what they do to their mages.
