Acts 21:21: Dispute and fierce contention springs

Dispute and fierce contention springs
From zeal for outward needless things,
With hasty error join'd:
Their tenets eager to defend,
Men will not patiently attend
To know each other's mind.

T is thus the legalists mistake,
And think that Moses we forsake,
And righteous works deny,
Who make the great salvation known,
And teach that God through faith alone
Doth freely justify.

Themselves the false conclusion draw;
We do not abrogate the law,
But its abuse remove
And fix it on a steadfast base,
And tell the faithful sons of grace
T is all fulfill'd in love.
