Analysis of information sources in references of the Wikipedia article "Missa tridentina" in Portuguese language version.
We decided to entrust this work to learned men of our selection. They very carefully collated all their work with the ancient codices in Our Vatican Library and with reliable, preserved or emended codices from elsewhere. Besides this, these men consulted the works of ancient and approved authors concerning the same sacred rites; and thus they have restored the Missal itself to the original form and rite of the holy Fathers. When this work has been gone over numerous times and further emended, after serious study and reflection, We commanded that the finished product be printed and published.
Que ninguém coma nem beba da Eucaristia sem antes ter sido batizado em nome do Senhor.(em inglês)
