RT Article T1 Order, Out of Order: Rahner's Tectonic Proposal for an Ecumenical Difficulty JF Horizons VO 42 IS 2 SP 341 OP 367 A1 Rinderknecht, Jakob Karl 1979- LA English PB Cambridge Univ. Press YR 2015 UL https://www.ixtheo.de/Record/166298720X AB The sacrament of order raises important ecumenical questions, but discussion is hindered by binding historical magisterial judgments of invalidity. This article examines a mostly overlooked ecumenical proposal made by Karl Rahner in 1974 for approaching the sacrament and examines its implications by applying the insights of contemporary cognitive linguistic thinkers. Rahner suggested that Protestant order could be ruled valid by the Catholic Church through a determination analogous to the radical sanation of a marriage. Such a proposal both accepts the prior judgment that the sacrament was invalid and declares it to now be valid retroactively to its beginning. Rahner's proposal has several important implications: first, it can allow for mutual recognition of ministries without requiring either a reordination of the other's presbyters or a revocation of the historical judgments of invalidity. Potentially more broadly, it can serve as the basis for a rethinking of sacramental causality in general.
