 This apparently came at the suggestion of Diego Valasquez, a monk and former knight who was "well acquainted with military matters", and proposed that the lay brothers of the abbey were to be employed as "soldiers of the Cross" to defend Calatrava.The initial successes of the new order in the Spanish Reconquista were brilliant, and the arrangement was approved by the General Chapter at Cîteaux and successive popes, giving the Knights of Calatrava their definitive rule in 1187.This was modeled upon the Cistercian rule for lay brothers, which included the evangelical counsels of poverty, chastity, and obedience; specific rules of silence; abstinence on four days a week; the recitation of a fixed number of Pater Nosters daily; to sleep in their armour; and to wear, as their full dress, the Cistercian white mantle with the scarlet cross "fleurdelisée".
