The principal instrument of ecumenism over the past half century has been a series of theological conversations between separated churches. Proceeding on the basis of what they held in common, the partners tried to show that their shared patrimony contained the seeds of much closer agreement than had yet been recognized. Rereading their confessional documents in light of Scripture and early creeds as shared authorities, they produced remarkable convergence statements on traditionally divisive subjects such as justification, Mariology, Scripture and tradition, the Eucharist, and the ordained ministry. The achievements of the Anglican-Roman Catholic International Commission (ARCIC), the Groupe des Dombes, and the World Commission on Faith and Order in its Lima paper on baptism, Eucharist, and ministry deserve our admiration. I personally stand by the ecumenical Âstatements that I have signed, including those of the Lutheran-Catholic Dialogue and of Evangelicals and Catholics Together.
And yet, valuable though it was, the convergence method was not without limitations. Each new round of dialogue raised expectations for the future. The next dialogue, at the price of failure, was under pressure to come up with new agreements. The process would at some point reach a stage at which it had delivered about as much as it could. It would eventually run up against hard differences that resisted elimination by this method of convergence.
When the dialogues attempted to go beyond convergence and achieve full reconciliation on divisive issues, they sometimes overreached themselves. Although not all would agree, I think the much vaunted Lutheran-Catholic Joint Declaration on Justification by Faith, signed in 1999, exaggerated the agreements. After stating quite correctly that the Lutheran and Catholic dialogues of previous decades had come to a basic consensus on the doctrine of justification by grace through faith, the Joint Declaration goes on to assert, more dubiously, that the remaining disagreements could now be written off as “differences of language, theological elaboration, and emphasis,” and therefore as not warranting condemnation from either side. It even described these differences as “acceptable.”
In my judgment, some of the unresolved differences are more correctly classified as matters of doctrine. Is the justified person always and inevitably a sinner worthy of condemnation in the sight of God? Are human beings able, with the help of grace, to dispose themselves to receive sanctifying grace? Can they merit an increase of grace and heavenly glory with the help of the grace they already have? Do sinners, after receiving forgiveness, still have an obligation to make satisfaction for their misdeeds? On questions such as these, Lutherans and Catholics seem to give incompatible answers. Nothing in the Joint Declaration persuades me that such differences are mere matters of theological speculation or linguistic formulation.
