"Chapter 51—A Faithful Under-Shepherd This chapter is based on the First Epistle of Peter . Little mention is made in the book of Acts of the later work of the apostle Peter. During the busy years of ministry that followed the outpouring of the Spirit on the Day of Pentecost, he was among those who put forth untiring efforts to reach the Jews who came to Jerusalem to worship at the time of the annual festivals. AA 514.1 As the number of believers multiplied in Jerusalem and in other places visited by the messengers of the cross, the talents possessed by Peter proved of untold value to the early Christian church. The influence of his testimony concerning Jesus of Nazareth extended far and wide. Upon him had been laid a double responsibility. He bore positive witness concerning the Messiah before unbelievers, laboring earnestly for their conversion; and at the same time he did a special work for believers, strengthening them in the faith of Christ. AA 514"
"Feed the flock of God which is among you, taking the oversight thereof, not by constraint, but willingly; not for filthy lucre, but of a ready mind;"
The EGW passage discusses Peter's role as a leader and shepherd in the early church, which aligns with the principle of shepherding and feeding the flock of God as described in 1 Peter 5:2. The chapter heading even states it is based on 1 Peter.
