Word Study

In depth

A plain-language study of iatrós — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Greek word iatrós, represented by G2395, is the term for a physician. It appears 7 times across 7 unique verses in the Bible. While it can refer to a literal medical practitioner, it is most notably used by Jesus in a metaphor to describe His mission to the spiritually ailing.

Biblical Occurrences & Contextual Analysis

In its literal sense, G2395 identifies the profession of Luke, who is called "the beloved physician" Colossians 4:14. The term also appears in narratives highlighting the limits of human medicine. In the accounts of the woman with the issue of blood, she "had suffered many things of many physicians" and spent all she had, but was not healed (Mark 5:26, Luke 8:43). The most frequent use of iatrós is metaphorical. Jesus uses the common understanding of a physician's role to explain His own purpose, stating that those who are well have no need of a physician, but the sick do (Matthew 9:12, Mark 2:17, Luke 5:31). Jesus also references the proverb, "Physician, heal thyself," showing its place in common dialogue Luke 4:23.

Related Words & Concepts

Several related words help clarify the role and context of the physician:

  • G2323 therapeúō: to wait upon menially, i.e. (figuratively) to adore (God), or (specially) to relieve (of disease):--cure, heal, worship. This is the action a physician performs. Jesus's disciples were given power to cure diseases Luke 9:1, and Jesus Himself was known for healing all manner of sickness Matthew 4:23.
  • G2480 ischýō: to have (or exercise) force (literally or figuratively):--be able, avail, can do(-not), could, be good, might, prevail, be of strength, be whole, + much work. This describes the state of being "whole" in Jesus's saying Mark 2:17 and is also used to state that the woman with the issue of blood could not be healed by any physician Luke 8:43.
  • G2560 kakōs: badly (physically or morally):--amiss, diseased, evil, grievously, miserably, sick, sore. This describes those who are "sick" and therefore in need of a physician (Matthew 9:12, Mark 2:17).
  • G5198 hygiaínō: to have sound health, i.e. be well (in body); figuratively, to be uncorrupt (true in doctrine):--be in health, (be safe and) sound, (be) whole(-some). This word is used for being "whole" in Luke's account of Jesus's metaphor Luke 5:31 and is also used figuratively for "sound doctrine" Titus 1:9.
  • G5532 chreía: employment, i.e. an affair; also (by implication) occasion, demand, requirement or destitution:--business, lack, necessary(-ity), need(-ful), use, want. This word is key to Jesus's teaching, as those who are whole have no need of a physician Luke 5:31.

Theological Significance

The theological weight of G2395 is centered on its metaphorical use by Christ.

  • Christ as the Great Physician: Jesus explicitly identifies His mission with that of a physician. His purpose is not for the righteous, but to call sinners who are spiritually "sick" Mark 2:17. This establishes a foundational understanding of His redemptive work as a ministry of healing.
  • The Limitation of Human Means: The story of the woman who suffered under many physicians without being healed serves as a powerful illustration. It contrasts the inability of human effort to solve a deep-seated problem with the immediate and complete healing that comes from Christ Mark 5:26.
  • Sin as Sickness: By using this metaphor, Jesus frames the condition of sinners as a spiritual disease. Those who are sick G2560 recognize their need G5532 for a healer, whereas the self-righteous, who consider themselves "whole" G2480, do not seek the help only the divine physician can provide Matthew 9:12.

Summary

In summary, G2395 is more than just a job title for a doctor like Luke. It is a vital theological concept used by Jesus Christ to define His own purpose on earth. The term powerfully contrasts the limits of human intervention with the divine power to heal. It illustrates that sin is a spiritual malady and that Jesus is the one true physician who can restore those who recognize their sickness and their need for Him.
