19 When the President of the Republic had promulgated his untimely and unjust decree of interpretation of the Constitution, by means of another joint pastoral letter the Bishops protested and pointed out that to accept such a law was nothing less than to desert the Church and hand her over a slave to the civil authorities. Even if this had been done, it was apparent to all that such an act would neither satisfy her persecutors nor stop them in the pursuit of their nefarious intentions. The Bishops in such circumstances preferred to put an end to public religious functions. Therefore, they ordered the complete suspension of every act of public worship which cannot take place without the presence of the clergy, in all the churches of their diocese, beginning the last day of July, on which day the law in question went into effect. Moreover, since the civil authorities had ordered that all the churches must be turned over to the care of laymen, chosen by the mayors of the different municipalities, and could not be held in any manner whatsoever by those who were named or designated for such an office by the bishops or priests, which act transferred the possessions of the churches from the ecclesiastical authority to that of the state, the Bishops practically everywhere interdicted the faithful from accepting a place on such committees bestowed on them by the Government and even from entering a church which was no longer under the control of the Church. In some dioceses, due to difference of time and place, other arrangements were made.
