21. Thus, after the present first book, the second expounds the mystery of the Divine birth, that those who shall be baptized in the Name of the Father and of the Son and of the Holy Ghost may know the true Names, and not be perplexed about their sense but accurately informed as to fact and meaning, and so receive full assurance that in the words which are used they have the true Names, and that those Names involve the truth.
21. Quid contineat liber secundus.---Post hunc enim primi hujus sermonis libellum, sequens ita sacramentum edocet divinae generationis, ut baptizandi in Patre et Filio et Spiritu sancto non ignorent nominum veritatem, neque vocabulis intelligentiam confundant, sed unumquodque ita sensu concipiant, ut est ac nuncupatur; agnituri absolutissime in iis quae dicta sunt, quod neque non ipsa veritas sit nominis, neque non nomen sit veritatis.
