What is the difference between the soul and the spirit?

Short answer

This is one of the genuinely debated questions in Christian theology, and the Bible does not settle it in a single verse. The words overlap heavily. Hebrew nephesh (H5315), usually translated "soul", ranges from breath and life to appetite to a whole living person, and is even used of animals (Genesis 1:20; Genesis 2:7). Hebrew ruach (H7307), usually "spirit", covers wind, breath and the animating or God-directed dimension of a person (Genesis 6:17; Ecclesiastes 12:7). The Greek pair behaves similarly: psyche (G5590) for soul or life, pneuma (G4151) for spirit or breath. They are frequently used interchangeably, Mary's song sets "my soul magnifies the Lord" in parallel with "my spirit rejoices" (Luke 1:46; Luke 1:47), classic Hebrew parallelism saying one thing twice. But two passages distinguish them, and they are the reason the debate exists: Paul's prayer that "spirit and soul and body" be kept whole (1 Thessalonians 5:23), and the word of God dividing "soul and spirit" (Hebrews 4:12). Two main positions are held across the traditions, and neither is a fringe view: dichotomy, that a person is material and immaterial and that soul and spirit name the same immaterial life from different angles; and trichotomy, that spirit, soul and body are three distinguishable parts. Both are set out below with their arguments, and no verdict is offered.

Word	Range of meaning	Examples
nephesh (H5315)	breath, life, appetite, a living creature, the whole person	Genesis 1:20; Genesis 2:7; Psalms 42:1
ruach (H7307)	wind, breath, spirit; the God-ward and animating dimension	Genesis 6:17; Ecclesiastes 12:7; Psalms 51:10
psyche (G5590)	soul, life, self	Matthew 16:26; Matthew 10:28
pneuma (G4151)	spirit, breath, wind	John 3:8; Romans 8:16

A detail that shapes the whole discussion: at creation God forms the man from dust, breathes into him the breath of life, and the man becomes a living nephesh (Genesis 2:7). The text does not say he was given a soul; it says he became one. Many read that as evidence the Bible treats a person as a unity rather than as parts assembled.

The case for dichotomy (two: material and immaterial)

The words are used interchangeably across Scripture, including in parallel lines that plainly mean the same thing (Luke 1:46; Luke 1:47).
Death is described as departure of the soul in some places (Genesis 35:18) and of the spirit in others (Luke 23:46; Acts 7:59), which is difficult if they are separate parts.
1 Thessalonians 5:23 is read as a prayer for the whole person, piling up terms for completeness in the same way as loving God with heart, soul, mind and strength (Mark 12:30), which nobody treats as four separate components.
Hebrews 4:12 is read as saying the word pierces to the deepest places, not as an anatomy of the person; the same verse also names joints and marrow.

The case for trichotomy (three: spirit, soul, body)

1 Thessalonians 5:23 names three things in sequence, and Paul chose to name three.
Hebrews 4:12 explicitly speaks of dividing soul from spirit, which implies a real distinction.
Some read 1 Corinthians 2:14; 1 Corinthians 2:15 and 1 Corinthians 15:44 as contrasting the psychikos (soul-ish, natural) person with the pneumatikos (spiritual) person, and take that as a real difference in kind.
On this view the spirit is the faculty by which a person relates to God, the soul is mind, will and emotion, and the body is the physical frame.

Where both sides agree

The agreement is broader than the dispute:

A human being is not merely a body, and not a soul imprisoned in a body. The biblical hope is bodily resurrection (1 Corinthians 15:42; 1 Corinthians 15:44), not escape from the physical.
Whatever the parts, Scripture treats the person as a unity in life and expects that unity to be restored in the resurrection.
The distinction, if there is one, is not a hierarchy in which the body is bad. The body is created good and is called a temple of the Holy Spirit (1 Corinthians 6:19).
Neither view changes anything about salvation. This is a question about human make-up, not about the gospel.

A note on where this often gets confused

Greek philosophy, especially in the Platonic tradition, held a sharp body-soul dualism in which the soul is the real person and the body a shell to be escaped. That is not the biblical picture, and both dichotomists and trichotomists say so. When people ask this question they are sometimes really asking whether the body matters, and on that the Bible is not ambiguous: it does.
