This text refers to the archibishop of lyon, an older brother of
cardinal richelieu. - Does it mean he was responsible for their
confession or simply that he was privy to their secrets?
Thank you

He said to keep the secret of the Spanish monks. -- Sorry, I don't
have enough context here to work out whether this is about confession
or not. Based on this, I would say that it is not, and I am unable to
find any mention of "le secret" meaning confession in any of my
dictionaries. It does seem to be referring to a particular secret,
rather than just "secrets" or "confession" though.
