Prof. Dennison even commented at the presentation of the book on this subject. He disagreed that Zwingli had a mere commemorative or memorial view of the supper. I found this here.
Zwingli now moved to abolish the Mass entirely. On Easter
Sunday (April 13, 1525), Zurich officially abolished the Mass. The Lord’s
Supper was instituted “in remembrance of ” the Lord Jesus’ atoning death; it
was not a bloodless re-sacrifice of Christ according to the Roman doctrine
and rite. Zwingli’s concept of the presence of Christ in communion was
certainly not corporeal (either by transubstantiation or consubstantiation),
yet he did maintain a Eucharistic presence in the Holy Spirit (“...but Christ
is present in the Supper by his Spirit, grace, and strength,”
42], VI, i, 758.33–36).
"I have taken all my good deeds, and all my bad deeds, and cast them through each other in a heap before the Lord, and fled from both, and betaken myself to the Lord Jesus Christ, and in him I have sweet peace."--David Dickson
