Paulinus of Nola

We find that arms have always needed faith, but faith has never needed arms. The rod of faith parted the sea which submerged the army bereft of faith together with its wicked leader.

Note how the teachers of the Old and New Testaments differ in their deeds but are paired in glory, for the one Wisdom issued twin laws in the two Testaments, so equal distinction gives the same weight to differing powers. Peter did not divide the sea with a rod, but then Moses did not walk on the waters. However, both have the same bright glory, for the one Creator inspired both the cleavage of the waters with a rod and the treading of the waves underfoot.
