Abstract: The debate regarding the unity of Church is, for the Western Europe, of Protestant origin, with an ecclesial communion model. This became an issue, once the Agreement of Leuenberg (near Basel) was signed by different Evangelic Churches, the bases for the Evangelic Church Communion in Europe or the Leuenberg Church Communion, today a structure of over 100 Churches and confessions. This study has the intention to present to the Romanian public this ecclesiological “experiment” of the last six decades. Its possible relevance for the present inter-confessional debate could consist in promoting the formula of reconciled diversity (versöhnte Verschiedenheit), among other effects.

Keywords: Leuenberg, Protestantism in Europe, models of unity, Orthodoxy, ecumenism
