Okay, got it. I’ll clip the paragraph to deal with the issue.I think this is the key and how you missed I can’t imagine because it plainly says **“places his hope in the legal prescriptions and submits himself to them as necessary for salvation” **Has Pope Francis indicated in any way that he holds that belief? No he has not. Issue resolved…case closed…by virtue of reading what is there in the text.
Okay…here again, read what is there. Has Pope Francis indicated anything like this? No he has not. Therefore your issue is resolved.
By the way…did you ever read in the New Testament about the Judaizers? You should and then you’ll have a proper context for reading this particular document.

I think I answered your issues. Until and unless Pope Francis tells us that we need to follow all the OT Law in order to be saved then there’s no problem. I wouldn’t hold my breath waiting for him to do that.
As for Yoga…I don’t see it as that good of an exercise program and I have seen too many practitioners get involved in Hinduism through it, (Though that also holds no interest for me…it just seems as pagan as the deities of Roman and Greek paganism.
One example I can relate to you is my long training in traditional Japanese Karate. I have read a great deal of ancient Japanese Budo material, (Budoshushinshu, Go Rin No Sho, and Hagakure) and found the philosophy of traditional Japanese martial arts to contain much wisdom in my studies. Zen was especially appealing though Buddhism or Shinto was not.
Anyone who cannot discern the difference between martial arts techniques and training and religion should find something else to do. Even the Hagakure tells us that the way of the Samurai and religion are not one and the same and should never become so to budoka.
Hopefully this clears things up for you.
