Praeparatio evangelica

Preparation for the Gospel (Ancient Greek: Εὐαγγελικὴ προπαρασκευή, Euangelikē proparaskeuē), commonly known by its Latin title Praeparatio evangelica, is a work of Christian apologetics written by Eusebius in the early part of the fourth century AD. It was begun about the year 313, and attempts to prove the excellence of Christianity over pagan religions and philosophies. It was dedicated to Bishop Theodotus of Laodicea.

Eusebius devotes a considerable portion of the work to explaining what he sees as a debt that Greek philosophers owed to Hebrew culture.
