“For example, there is a thread on the Catholic Answers web site that addresses Augustine’s Sermon #227,”
Your quote only makes a bland assertion as a matter of faith, and then says some gibberish as if it proves that what they confess Augustine understood as symbolism, was still somehow also a reality. It doesn’t actually answer anything I posted from sermon 227 that shows a very radical and different view to the sacraments. I myself would consider using Augustine’s use of the sacraments in church service, such as the “sacrament of the Holy Spirit,” or a variant on the “sacrament of the kiss of peace,” since they are quite rich in setting the mind to understand the ultimate realities that they are meant to teach.
“then says some gibberish”
Yet Christ himself says and turns away those who refuse to eat of his flesh and drink of his blood!
