What the Bible says about Pias
(From Forerunner Commentary)
Only Matthew and Luke record the miracle of the healing of a centurion's servant (Matthew 8:5-13; Luke 7:1-10). Both accounts indicate that the afflicted servant who needed Jesus Christ's help was young. Luke uses the Greek word doulos, meaning bond slave, someone born into slavery (Luke 7:2). Matthew, however, uses pias, meaning a child or young person (Matthew 8:6). The context indicates that this servant was not a little boy but a young man still in his teens.
The servant's master was a centurion, a Roman soldier in charge of one hundred soldiers of the Roman garrison in Capernaum. Several centurions recognized Christ's special purpose and honored Him (Mark 15:39; Acts 10:1; 22:25-26; 27:1, 43; 28:16). This miracle reveals that faith is sometimes found where we least expect it.
Although Matthew and Luke generally agree in their accounts of this incident, some differences occur. Matthew, a Jew, seems to have Israel in mind as he records Christ's somber warning to the nation not to neglect personal responsibility and to put their faith and hope in God instead of civil and religious institutions of man. They were in serious need of humility (Romans 12:16).
On the other hand, Luke, a Greek, had fellow Gentiles in mind, so excluding the warning to Israel, he instead encourages the proud Gentiles to ask for the help they needed for their problems. He does this by showing that a centurion was able to persuade the Jewish elders to help in pleading to Jesus for his servant. Humility is necessary for happiness in life (Psalm 69:32).
