22 We wish to pay a special tribute of praise to those members of the clergy, secular and regular, and of the Catholic laity, who, moved by burning zeal for religion and maintaining themselves in close obedience to this Apostolic See, have written glorious pages in the recent history of the Church in Mexico. At the same time We exhort them earnestly in the Lord to continue to defend the sacred rights of the Church with that generous abnegation of which they have given such a splendid example, always following the norms laid down by this Apostolic See.
