New Testament: Christ and the Apostles instituted no new worship of angels or saints
Under the New Testament, Christ and the Apostles changed nothing at all in this respect. They instituted no new worship by which angels and the spirits of the righteous, admitted to the sight of God's face, were from then on to be worshiped. There is no command, no example, not even the slightest hint of it anywhere in the New Testament. Nowhere are we told there to invoke angels or departed saints, to run to them for help, to sing hymns to them publicly, or to honor them with frankincense and incense, altars and churches, or any other outward acts of adoration.
Latin
LIX. Sub Novo vero Testamento Christus & Apostoli hac in parte nihil omnino immutarunt. Nec ullum novum cultum instituerunt, quo deinceps Angeli & Justorum Spiritus ad videndam Dei faciem admissi colerentur. Etenim hujus rei nullum praeceptum, aut exemplum, vel etiam minimum indicium apparet in tota Novi Testamenti Scriptura. In qua nullibi monemur Angelos aut Sanctos defunctos invocare, ad eorum opem confugere, hymnos illis publice canere, eosque thure, incenso, altaribus & aedibus sacris, aut quibuslibet aliis externis adorationis actibus honorare.
