[Hermogenes] despises God's law in his painting, maintains repeated marriages [almost certainly a reference to remarrying after divorce or perhaps even widowhood, which Tertullian, who became a Montanist, opposed], alleges the law of God in defense of lust [likely same reference], and yet despises it in respect of his art.
TertullianAll the Scriptures give clear proof of the Trinity, and it is from these that our principle is deduced...the distinction of the Trinity is quite clearly displayed.
TertullianOfferings to propitiate the dead then were regarded as belonging to the class of funeral sacrifices, and these are idolatry. Idolatry, in fact, is a sort of homage to the departed, the one as well as the other is a service to dead men. Moreover, demons dwell in the images of the dead. ... this sort of exhibition has passed from honors of the dead to honors of the living; I mean, to quaestorships [financial overseers]and magistractes, to priestly offices of different kinds. Yet, since idolatry still cleaves to the dignity's name, whatever is done in its name partakes of its impurity.
