1580 was an important year in the resolution of the disputes within the Carmelites. On 22 June, Pope Gregory XIII signed a decree, titled Pia Consideratione , which authorised a separation between the Calced and Discalced Carmelites. The Dominican friar Juan Velázquez de las Cuevas was appointed to carry out the decisions. At the first General Chapter of the Discalced Carmelites, in Alcalá de Henares on 3 March 1581, John of the Cross was elected one of the "Definitors" of the community, and wrote a set of constitutions for them.  By the time of the Provincial Chapter at Alcalá in 1581, there were 22 houses, some 300 friars and 200 nuns in the Discalced Carmelites.
