Maybe I can chime in. In
my master’s thesis, where I analysed and discussed the sacrificial aspect of the Eucharist in the systematic theology of Lutheran theologian Wolfhart Pannenberg and Catholic theologian Joseph Ratzinger (better known as pope Benedict XVI), I concluded (pp.114-119) that a ‘sacrifice of the Mass’ is acceptable, on a Lutheran understanding. I summarised my point in six points (p.118):
If we hold (1) that Christ is actually present in the Eucharistic elements, (2) that Christ is offering himself in the heavenly sanctuary, presenting himself on our behalf, (3) that the Church offers her Eucharistic sacrifice of praise and thanksgiving in and through Christ who is presenting himself on our behalf, (4) that the priest, as he presides in the Eucharistic celebration, is acting
in persona Christi, (5) that we participate in the ‘heavenly liturgy’ through the Eucharistic celebration, and (6) that the anamnesis, the Eucharistic prayer, the center of which is the institution narrative, is primarily directed towards God, it follows quite coherently that the Eucharist is a sacrifice that is offered unto God in the Eucharistic celebration.
These are the points that needs to be adressed. Because if each of these are true, then it follows that the Mass is a sacrifice as in a participating in Christ’s ongoing, perpetual offering in the heavenly sanctuary (cf.
Heb. 8:1-3)
