“the new doctrine of ‘faith alone”
So would you consider Polycarp a “new doctrine”?
Polycarp 1:3
for as much as ye know
that it is by grace ye are saved, not of works, but by the will of
God through Jesus Christ.
Polycarp 9:2
being persuaded that all these ran not in vain but in faith and
righteousness,
Polycarp 12:2
Now may the God and Father of our Lord Jesus Christ, and the eternal
High-priest Himself the [Son of God Jesus Christ, build you up in
faith and truth,
The original was “Faith Alone” brought to you by Jesus Christ, His Apostles, and protestants.
Neither is the book of St. Polycarp mentioned in what the Protestants call the apocrypha. I do find that St. Polycarp apparently received as the other Church Fathers did, letters written by and shared by St. Paul, St. Peter, and other communications amongst the Church leaders at that time. I therefore can and do consider him an ancillary source to what's in my Bible. I do also regard it my duty to my God to consider the full Bible in my endeavor to understand and pass on my faith. I find it totally unproductive to cling to a single verse or verses without considering the whole Word of God.
I believe it absolutely necessary to remind myself and others that St. Paul had spent long periods of time in teaching the churches that he had established. And so I rely more heavily of what Jesus said, with all ties going to Jesus rather than to put Jesus' teachings aside in favor of St. Paul's. After all St. Paul in his letters could do no more than hit the highlights.
