Eucharist as a Celebration of Forgiveness

Francis Moloney’s new book is an in-depth study of the history and theology of the Eucharist as primarily a celebration of forgiveness rather than as a tool for exclusion, and the ethical consequences that arise from such a study.
The author first tracks how we came to the exclusive and need for holiness criterion for admission to the eucharistic table. This must begin with 1 Cor 11, and then see where it goes from there-historically and theologically. Here a note on its eventual application to marriage relating to the exclusive and need for holiness criterion for admission to the eucharistic table.
He then gives a summary of how all the gospel narratives indicate the celebration of forgiveness.
Next he focuses on the history and theology of legitimate exclusion from the eucharistic table. This needs to be covered, as from the second century it is practiced, and is probably already there in 1 Cor 5 (the incestuous man). The motive for this, however, is always the denial of God, Christ, and/or Church. This position has a legitimate theological correctness.
Lastly, he explores a theology of Eucharist as forgiveness and its ethical consequences. Marriage and other sexuality questions can be part of the debate.
