The Swedish Church Ordinance of 1571 was the first complete Swedish church order following the Swedish Reformation in the 1520s. The main originator of the ordinance was archbishop Laurentius Petri. Petri had been archbishop since 1531 and had published many doctrinal texts. He had in vain tried to persuade kings Gustav Vasa and Eric to be allowed to publish a complete church ordinance. With the ascension of King John in 1568, Petri was granted permission, and in 1571 published Canon Ecclesiasticus. It was formalized at a church meeting in 1572.
