Ignatius of Antioch- Declared that the eucharist was 'the medicine of the immortality and antidote that we shall not die but live forever in jesus christ' he stated the Eucharist is somehow insturmental in effecting eternal life therefore heavily relying on Augustines 3rd requirement of th definition of a sacrement that it must bestow efficicay and totally disgrgarding and going against zwingli's view who emphasized on the idea that a sacrement is mearly just a symbol or sign and has no efficacy or "cause grace" in the strict sense of the word but god effects or may cause grace at the presence of a sacrement.
