Zeal is very blind, or badly regulated, when it encroaches upon the rights of others.

I have more zeal than wit.

Zeal then, not charity, became the guide.

Poets heap virtues, painters gems, at will, And show their zeal, and hide their want of skill.

Zealous men are ever displaying to you the strength of their belief, while judicious men are showing you the grounds of it.

But zeal moved thee; To please thy gods thou didst it!
