 His office drafted a pact called the "arreglos" ("agreement"), which allowed worship to resume in Mexico and granted three concessions to the Catholics.Only priests who were named by hierarchical superiors would be required to register; religious instruction in churches but not in schools would be permitted; and all citizens, including the clergy, would be allowed to make petitions to reform the laws.However, the most important parts of the agreement were that the Church would recover the right to use its properties, and priests would recover their rights to live on the properties.
