Joseph Hellerman offers an interesting insight into this passage that commentators identify as one of the “high Christological passages” of the New Testament (alongside John 1:1-4; Col. 1:15-20; Heb. 1:1-3). He demonstrates that though the hymn clearly has much to say about the subject of Christology, the hymn is first and foremost ecclesiological. He writes
This is because of Paul’s opening appeal to the brothers and sisters in Philippi to “have this mind in you” (v.5). Jesus’ humility in his self-emptying (ἐκένωσεν) involved him stooping lower and lower until he reached the lowest rung of the social hierarchy in the first century. Paul begins his appeal to the church by first calling attention to the “equality” that Jesus relinquished. In his self-emptying, Jesus did something mentally – he did not “count” his “equality with God” something “to be grasped” (v.6). Thus, his first action in the redemption of humanity was not first in the incarnation, nor his humiliation on Good Friday. Rather, it was in his mind. The Christ, in his estimating, concluded that he would temporarily release his rightful place of glory. In order for Paul to appeal to the “mind” of the church, he first appealed to the “mind” of Christ in his “counting” and “considering.” In a culture in which honor and status were prized above all, this would have struck the early readers as utterly unfathomable. The Divine Son of God of his own volition became a slave. Jesus’s entering as a person, in a specific place, assumed the position of the despised.
