17 At any rate, let no one distort the meaning of Our present decision in a way which is quite foreign to Our thoughts to the effect that by it We desire to nullify the condemnation of Associations made by Our Predecessor of saintly memory, Pius X, or that We have become reconciled to the so-called "Lay Laws." Whatever Pius X condemned, We condemn; wherever and as often as the term "lay" is understood in the sense of a feeling or ideal inimical or foreign to God and to religion, We absolutely condemn such a thing and declare moreover to the whole world that such "laicism" must be condemned. Nor let anyone say that the permission to exist, which We accord to the Diocesan Associations, is in itself an overturning of the orders of Pius X, for the simple reason that the orders of Pius X referred to entirely different matters existing in circumstances altogether different from the present.
