If ' a ray of the Truth' (NA 2) is considered visible or invisible decides heresy

If ‘ a ray of the Truth’ (NA 2) is considered visible in the flesh to us then it contradicts the thrice defined dogma extra ecclesiam nulla salus. It is heresy.
If ' a ray of the Truth' is considered not visible to us human beings then it is not relevant to extra ecclesiam nulla salus. It refers to a possibility of salvation, only known to God. It is a probability but not an exception.

Similarly if being saved in invincible ignorance (LG 16) is considered explicit for us , then it means there is salvation outside the Catholic Church. It means every one does not have to be a visible member of the Church for salvation. This is heresy.
It is invisible for us. Rationally we know NA 2  is not in conflict with the de fide dogma.-Lionel Andrades
