What does Wisdom Chapter 15 say, and which statements belong to its speaker?

Wisdom 15's collective voice praises God as gracious, true, patient and mercifully ordering all. If they sin they remain his knowing his greatness; if not they know they are counted with him. Knowing God is perfect justice and knowing his justice and power immortality's root. They say mischievous inventions, picture-shadows and colored figures have not deceived them, although fools lust after dead images. Makers, lovers and worshippers of evil things deserve no better trust.

A potter shapes both clean-use and contrary-use vessels from the same clay, deciding their function. He vainly makes a god from it though himself earth-made and soon returning when his lent life is recalled. His concern is rivalry with goldsmiths, silversmiths and brass workers and glory in vain things, not short life or labor. The author calls his heart ashes, hope vain earth and life baser than clay because he does not know his maker, giver of working soul and living spirit. Those treating life as pastime and gain seek even evil profits; the maker of brittle vessels and graven gods knows he offends above others. The verse does not say he transforms vessels into gods or mass-produces cheap terracotta.

Enemies subjecting God's people are called foolish, unhappy and immoderately proud for treating idols as gods despite eyes, noses, ears and hands unable to function and feet slow to walk. A human borrowing breath made them and cannot make a god like himself. Living mortal makers are better than the dead objects that never lived, not infinitely superior by a new scale. The passage also condemns worship of vile creatures, explicitly saying senseless things compared with these are worse. It closes with no visible good in those beasts and departure from God's praise and blessing, without reversing that comparison or adding a universal human-animal hierarchy.
