Such unity will only come when Christians are humble and bold enough to lay hold on the unity already given in Christ and to take it more seriously than their own self-importance … and to make of those deep differences of doctrine, which originate in our imperfect understanding of the Gospel and which we dare not belittle, not an excuse for letting go of one another or staying apart, but rather an incentive for a more earnest seeking in fellowship together to hear and obey the voice of Christ.

—C. E. B. Cranfield, The First Epistle of Peter, 75-6.
