Latria and dulia: a school distinction both sides can tolerate
We have also shown that the teachers of the Roman school admit that the division of religious worship into latria and dulia is an invention of the schools, and that Scripture does not strictly keep the difference between these words as the Roman school uses them. Dulia is more often confined there to the worship proper to God, while latria is sometimes extended to service rendered to human beings.
The teachers of the Reformed school, for their part, do not much object if, for clarity's sake, latria is assigned to divine worship and dulia to the respect with which creatures may and should be honored.
Latin
LIII. Illud quoque a nobis ostensum, Doctores Scholae Romanae fateri, distinctionem cultus Religiosi in Latriam & Duliam esse Scholae inventum; nec vocum istarum discrimen, prout in Schola Romana usurpantur, in Scriptura exacte servari: Duliam enim saepius ad cultum Deo proprium restringi, Latriam vero aliquando ad servitium humanum extendi. Vicissim autem Scholae Reformatae Doctores non multum repugnare, quin distinctionis causa, Latria divino cultui, Dulia vero observantiae illi, qua creaturae coli possunt & debent, accommodetur.
