Tradition: Medieval Latin theology / scholasticism
Why God became man — Anselm's rational argument for the necessity of the Incarnation, founding text of satisfaction theory of atonement
Cur Deus Homo (Why God Became Man) is Anselm's c. 1094-98 systematic dialogue arguing for the rational necessity of the Incarnation. Its thesis: human sin against the infinite dignity of God constitutes an infinite debt that no finite creature can pay; only an infinite being can pay it; only God can do so; but the debt is owed by humans; therefore only a God-man can pay it; hence the necessity of the Incarnation. Founding text of the "satisfaction theory" of atonement that shaped Western Christian soteriology through Aquinas to the Reformation.

School Embodiments
Founding text of Catholic satisfaction-atonement theology; shaped Aquinas's ST III.
"There must be infinite satisfaction for an infinite offense; this only the God-man can pay." (Cur Deus Homo II.6)
Anselm's "rational necessity" argument — fides quaerens intellectum applied to atonement.
"I do not seek to understand in order to believe; I believe in order to understand." (Anselm, Proslogion — methodological background)
Reformation atonement theology (Calvin, penal substitution) descends from Anselm's satisfaction framework.
"The infinite debt requires infinite payment; this is the foundation of all Christian soteriology." (Cur Deus Homo)
Realist about sin, debt, satisfaction — these are real conditions requiring real response.
"Sin is not merely subjective wrong but an objective debt to the divine order." (Cur Deus Homo II.4)
Aristotelian-Augustinian framework (substance, accident, person) operates in the Christological analysis.
"The God-man is one person in two natures; this the doctrine of the Incarnation requires." (Cur Deus Homo)
The Greek-patristic ransom-theory of atonement was the alternative Anselm rejected; the East has not adopted Anselm's satisfaction model.
"The ransom paid to the devil — as some Fathers have said — cannot be correct; the debt is owed to God." (Cur Deus Homo I.7)
Internal Tensions
Satisfaction-atonement theology has been criticised (Abelard's exemplarist alternative, modern liberal theologians, feminist theologians) for its juridical framework; the Eastern Orthodox tradition has never accepted it. Continuing debate.
