GERARD (GERARDINO) of BORGO SAN DONNINO. — He was teaching grammar when he took the Franciscan habit. Already a follower of the Joachimite theories, he was sent to Paris to study theology (1248).
In 1254 he published without permission the *Concordia Novi et Veteris Testamenti* of the Calabrian abbot, along with the *Liber introductorius ad Evangelium aeternum*. This latter work gives a false idea of the Eternal Gospel, which is no longer the spirit of the two Testaments, but is materialized in the triple work of Joachim: *Concordia*, *Expositio in Apocalypsin*, and *Psalterium decem chordarum*.
The work provided an opportunity for a most dangerous offensive against the Mendicants in the University, and was censured by Alexander IV (1255). G. returned to Sicily; continuing, and sent again to Paris, he was condemned by the Minister General, St. Bonaventure, to perpetual imprisonment, and died 18 years later unrepentant. Angelo of Chiarino asserts that he was one of the principal companions of the Blessed John of Parma.
