“It was once my chief desire, dearest friends, to enjoy the spectacle of your united presence; and now that this desire is fulfilled, I feel myself bound to render thanks to God the universal King, because, in addition to all his other benefits, he has granted me a blessing higher than all the rest, in permitting me to see you not only all assembled together, but all united in a common harmony of sentiment. I pray therefore that no malignant adversary may henceforth interfere to mar our happy state; I pray that, now the impious hostility of the tyrants has been forever removed by the power of God our Saviour, that spirit who delights in evil may devise no other means for exposing the divine law to blasphemous calumny; for, in my judgment, intestine strife within the Church of God, is far more evil and dangerous than any kind of war or conflict; and these our differences appear to me more grievous than any outward trouble. Accordingly, when, by the will and with the co-operation of God, I had been victorious over my enemies, I thought that nothing more remained but to render thanks to him, and sympathize in the joy of those whom he had restored to freedom through my instrumentality; as soon as I heard that intelligence which I had least expected to receive, I mean the news of your dissension, I judged it to be of no secondary importance, but with the earnest desire that a remedy for this evil also might be found through my means, I immediately sent to require your presence. And now I rejoice in beholding your assembly; but I feel that my desires will be most completely fulfilled when I can see you all united in one judgment, and that common spirit of peace and concord prevailing amongst you all, which it becomes you, as consecrated to the service of God, to commend to others. Delay not, then, dear friends: delay not, ye ministers of God, and faithful servants of him who is our common Lord and Saviour: begin from this moment to discard the causes of that disunion which has existed among you, and remove the perplexities of controversy by embracing the principles of peace. For by such conduct you will at the same time be acting in a manner most pleasing to the supreme God, and you will confer an exceeding favor on me who am your fellow-servant.”
The earnest desire of Constantine to promote peace in the church makes one judge with leniency the rather arbitrary and very mechanical method he often took to secure it. As over against the unity of form or the unity of compromise, there is one only real unity—a unity in the truth, being one in the Truth. The secret of peace is reason with right.
