Moses ha-Kohen de Tordesillas
Spanish Rabbi

Moses ha-Kohen de Tordesillas (fl. 1370s) (Hebrew: משה הכהן) was a Spanish Jewish controversialist of the fourteenth century.
An attempt was made to convert him to Christianity by force. Despite persecution, he remained true to his convictions, although he was robbed of his possessions and reduced to poverty. He was chosen rabbi by the community of Ávila.
He was forcefully made to participate in a religious debate, around the year 1372, with the Jewish convert to Christianity John of Valladolid, in the presence of Christians and Muslims. Moses was acquainted with the Christian sources, and refuted in four debates the arguments of his opponent, who tried to prove the Christian dogmas from the Scriptures.
Soon afterward he was obliged to enter upon a new contest with a disciple of the convert Abner of Burgos, with whose writings, especially with his Mostrador de Jeosticia, Moses was thoroughly acquainted. In 1374, at the desire of the members of his community, he wrote, in the form of a dialogue between a Jew and a Christian, the main substance of his debates, which treated of the Trinity, of the virginity of Mary, of sacrifice, of the alleged new teachings of Jesus and of the New Testament, of the seven weeks of Daniel, and of similar matters. His book, which is divided into seventeen chapters, dealing with 125 passages emphasized by Christian controversialists, is entitled "'Ezer ha-Emunah" (The Support of Faith אמונה).
This brief starts where responsible research should: with the source description of “Moses ha-Kohen de Tordesillas” as spanish Rabbi. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as spanish Rabbi. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 31, 2026. The linked authority identifier is Q1949059. VIAF identifies the subject as 32797829. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1372 and 1374.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
