“The Church as Koinonia of Salvation: Its Structures and Ministries”  recommends that Lutheran and Catholic:
bishops have retreats together, priests and pastors have mutual sermon preparation study as well as lay catechesis, evangelization, peace and justice ventures, social ministry, and attendance at each other’s diocesan and synodical assemblies"
Doesn’t that suggest significant unity between Lutherans and Catholics?
The Church as Koinonia of Salvation: Its Structures and Ministries
- We recommend that our churches recognize the real but imperfect communion among our ministers and encourage appropriate forms of pastoral collaboration between our ministries. Specifically, we propose:
that common activities among Lutheran and Roman Catholic bishops be promoted in order to signify the level of communion that exists between them, such as regular joint retreats, co-authored pastoral letters on topics of mutual concern, and joint efforts on matters of public good;
that mutual activities be intensified among ordained ministers, such as regular retreats, homily or sermon preparation study, participation in non-eucharistic prayer services and weddings, and common sponsorship of events or services in the life of the church, including as appropriate other leadership ministries;
that the faithful, in light of their common baptism into the people of God, engage together in catechesis, evangelization, peace and justice ventures, social ministry, and attendance at each other’s diocesan and synodical assemblies; and
that social ministry organizations, educational institutions, chaplaincies, and other church agencies engage together in activities that further the gospel and the common good.
