The Capuchin Constitutions of 1536 - text only
So that our Congregation, as the vineyard of the Son of God, persevere in the spiritual observance of the evangelical and seraphic Rule, our General Chapter celebrated in the City of Rome at our place in Saint Euphemia in the year of the Lord 1536 believed it should set down some statutes as a hedge for that Rule. Like the impregnable Tower of David it should have its fortifications with which we may defend ourselves from all the enemies of the living spirit of our Lord Jesus Christ, and from all the compromises against the most fervent and seraphic zeal of our Father Saint Francis. (Introduction, Constitutions of 1536)
These Constitutions, published in Naples in 1537, had been lost until 1926. They were republished in Liber Memorialis Ordinis Minorum Capuccinorum, Rome, 1928. More recently, a photographically reproduced (or anastatic) version came to light in Constitutiones Ordinis Fratrum Minorum Capuccinorum saeculorum decursu promulgatae, Vol.I: Constitutiones Antiquae (1529-1643), Editio Anastatica, Rome, Capuchin General Curia, 1980, p. 35-74.
