Yes, Tan Books (or more specifically, Thomas Nelson, publisher of Tan Books) IS “traditionalist.” Even more specifically, he is a schismatic member of the spurious Chivalric Order - the Sovereign Military Order of St John of Jerusalem.
The Chaplain of the OSJ is Father James Wathen, O.S.J., who was described by a friend of ours, Franciscan br. Alexis Bugnolo, as “formerly being a Catholic priest.” Fr. Wathen is, of course, the author of “The Great Sacrilege” which sets out to prove that the Novus Ordo Missae IS a Sacrilege and no Mass at all.
"Fr. Wathen’s “The Great Sacrilege” was printed, published and sold by his buddy in arms, Thomas A. Nelson, O.S.J, of TAN Books.
Also published by Tan Books is
- Wathen’s “Is the Society of St John Masonic?”
- Fr. Anthony Cekada’s “The Ottaviani Intervention.” Cekada is former SSPX priest, former SSPV priest, now CMRI/Thucite adherent.
I think (but am not sure) he also published “Fr.”/Dr Rama Coomaraswamy’s “The Problems With the New Mass.”

My advice is to purchase your books from a reliable Catholic supplier - even if it costs more.
