“Consider how contrary to the mind of God are the heterodox in regard to the grace of God which has come to us. They have no regard for charity..They abstain from the Eucharist and from prayer, because they do not admit that the Eucharist is the flesh of our Savior Jesus Christ, the flesh which suffered for our sins and which the Father, in His graciousness, raised from the dead.”
(St Ignatius of Antioch, Letter)
