To match his learning and his wit;

For he was of that stubborn crew
Of errant saints, whom all men grant
To be the true Church Militant;
Such as do build their faith upon
The holy text of pike and gun;
Decide all controversies by
And prove their doctrine orthodox,
By Apostolic blows and knocks.

- O how far remov'd,
Predestination! is thy foot from such
As see not the First Cause entire: and ye,
O mortal men! be wary how ye judge:

The number of the chosen; and esteem
Such scantiness of knowledge our delight:
For all our good is, in that primal good,
Concentrate; and God's will and ours are one.

In the cause of mankind, if our creeds agree?
Shall I give up the friend I have valued and tried,
If he kneel not before the same altar with me?

To seek somewhere else a more orthodox kiss?
No! perish the hearts, and the laws that try
Truth, valour, or love, by a standard like this!

An emblem yields to friends and enemies
How the bold teacher's doctrine, sanctified
By truth, shall spread throughout the world dispersed.
