The struggle at the Reformation was less like the present, either in its
causes or its course, but it has some features which make it a useful
point for a survey of the permanent unifying elements which hold and
will hold the West together in spite of occasional cataclysms and the
clash of rival interests and passion. A man like Erasmus, trembling
before the catastrophe, willing to make immense sacrifices to avoid an
open breach, uncertain of any final readjustment which might restore the
harmony of the world, was not unlike some among us who hoped against
hope that the enemy might be appeased, who thought that almost any peace
was better than any war, who still fear that the breach in unity is
vital or irreparable for generations.

And the issue three hundred years ago may also inspire us with a
cautious optimism, a strong though not unmeasured trust. The right cause
triumphed, fully in the end. Freedom was secured, both for churches and
for individuals, throughout the world. The evil features in the papal
system, against which the attack was really levelled, quietly but
completely disappeared, and the institution survived, itself reformed.
Before a hundred years were out the world had moved on to the conquest
of new vantage points and the establishment of a wider unity on a firmer
base.

Both previous occasions are therefore full of hope. The European system

any civilized order embracing the whole world; and the great convulsions
which have hitherto continued to occur in it from time to time are
moments of especial value for the study of the conditions under which it
exists. They are the pathological experiences which reveal the strength
and the weaknesses of the normal functions. We strive and hope for a
more lasting state of general health, and do not despair of the patient
