Bond(-man) and servant are the words translated from doulos (1401), 'a slave', literally and figuratively, voluntarily and involuntarily, frequently therefore in a qualified sense of 'subjection' or 'subserviency'. Paul utilizes the term in several of his writings to convey his position toward Christ. From my personal understanding, an individual could often be enslaved to another for various reasons and in multiple manners in Jewish society--but many (perhaps all) had a time when freedom could be obtained, either through forgiveness or redemption or as a matter of Jewish law. That person could obligate himself voluntarily, making that person a bond servant, and so denoted by a piercing in the lobe of the ear. I believe that in most cases of slavery, the enslaved is exhausted of most individual rights, so they served at the pleasure of their masters. The master was expected to provide sufficient living conditions for the enslaved, who were considered personal property of the slave masters or owners. Under Jewish law, slaves were afforded the Sabbath rest, as they were a part of the Jewish master's household. As a believer, follower and ambassador of Christ, Paul used the picture of the bond servant to represent how he felt toward the Christ in terms of Him being his Lord, master, provider and protector. In writing to the people at Corinth, Paul would say to them "...you are not your own. You are bought with a priceā¦." (1 Cor 6:19-20), meaning that the free gift of salvation given to us was actually paid for by Christ death on the cross to pay our wages (of death) for us. Paul feels that he owns no less than to become a bond servant to Jesus Christ.
Saint and (most) holy (one, thing) are the words translated from hagios (40), 'sacred', physically 'pure', morally 'blameless' or 'religious', ceremonially 'consecrated'. This is a term that is used throughout the New Testament to referred to Christ's followers. From my personal understanding, the term is universally applicable to anyone who accepts Christ's free gift of salvation and makes Christ Lord of his/her life. The term is one referencing an individual's standing with the Lord--not of righteousness through one's own accountability but by Christ's death on the cross as a perpetual payment for our sins. It is a remarkable truth that Christ paid for our past sins, the ones we may be committing in the moment, and any which we will commit in the future until we are freed from the presence of sin of this world.
