Body, soul, mind, will. 

Think for one second about the Sacrament of Confession.

To go to confession spurs on a marvelous, multi-element reconciliation.

Penitent to God (via prayer)
Penitent to Church (via priest)
Penitent to neighbor (penance and reparation)

To simply go to Confession requires an "integral" coordination of mind, will, body.

To put one's sins into words is an act of the intellect.  The will moves the person, the body follows, the intellect is forced to articulate and "name" sins, the will tells the intellect to comply with the priest by making an act of contrition, the body cooperates.

A marvelous "re-unification" occurs.

That's one aspect of "integrally human"
