“Faith, therefore, allows the greatest latitude in philosophic speculation, allowing us without blame to think what we like about anything.”
Meaning & context
Spinoza separates faithful conduct from enforced uniformity of speculation: people can differ widely in philosophical belief while still being judged by whether their teaching leads toward justice and charity rather than hatred.

A Theologico-Political Treatise — Part III, Chapter XIV, paragraph 77, Project Gutenberg #991. The frozen catalog preserves the opening of Spinoza’s longer sentence; the paragraph continues by condemning teachings tending toward obstinacy, hatred, strife and anger and praising justice and charity. This is seventeenth-century theological / political philosophy, not a modern empirical claim.

Ethics, Part V, Proposition XLII, R. H. M. Elwes translation represented by Project Gutenberg #3800. ‘Blessedness is not the reward of virtue, but virtue itself’ introduces Spinoza's proposition linking blessedness, knowledge, virtue and control of the emotions. It remains translation-mediated seventeenth-century metaphysical ethics, not a universal psychological measurement or clinical prescription.

“the terms good and evil are only applied relatively, so that the same thing may be called both good and bad according to the relations in view,”
Meaning & context
Spinoza asks readers to examine evaluative terms in relation to purposes and comparisons instead of assuming that every judgment of good or bad names an absolute property.

On the Improvement of the Understanding, section 12, Project Gutenberg #1016 in R. H. M. Elwes's public-domain English translation. Spinoza says the terms good and evil are applied relatively while introducing his distinction between ordinary relative goods and the true/highest good sought by the unfinished treatise. It remains translation-mediated seventeenth-century methodological philosophy rather than a claim that all moral distinctions are meaningless.
