As far as I can see J.P.Holding did not say that Massey did not reference sources sometimes. The problem is that often these sources are invalid such as the Toledeth Jeshu for example as Holding demonstrates. Secondly he often does not
provide sources for his claims and in particular primary sources which is what is required.
For example as Holding points out Massey claims various titles for Horus such as Good Shepherd,Lamb of God etc which you will find in Holding's critique. He says that the only sources he could find for these were esoteric sources. He then challenges Massey supporters to produce these alleged titles in the original
contexts, that is the primary Egyptian sources.
Enough of the evasion Robert. Have a look at these titles Massey claims for Horus which Holding quotes him on and provide the primary sources for them in the ancient Egyptian texts.
You simply refuse to answer the challenge and think merely by saying that Massey provides some references and sources,(though he doesn't provide primary sources in the areas Holding challenges) you can evade specific questions and simply refuse to answer them.
You can fool yourself all you like but if you are not prepared to be specific and answer specific challenges and questions with references to primary sources, this conversation is over as far as I'm concerned.
