Are you playing 'Gotcha' lol?go with that then, and elsewhere describe how those with Torah could not have been saved if you like, neverminding that you are assuming here that Z even went to temple.

By Word, I mean verbal or written. Especially for us today, what we hear verbally must accord with what is written, whether by dream, vision, or spoken word.
Here is an example...
But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
(Gal 1:8-9)

These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
(Act 17:11)
