“Faith, therefore, allows the greatest latitude in philosophic speculation, allowing us without blame to think what we like about anything.”
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.
