Are icons borrowed pagan or Platonic religion?

Apologetics

Shared visual forms or vocabulary do not decide a practice's truth; their meaning and use must be examined.

Key points

Image-prototype language, halos, and Christian symbols resemble pagan art and philosophy. The theology may be a later pagan import.
Christian teaching can use a familiar artistic form without adopting the religion that once used it. The same is true of language and architecture.
The Fathers' image arguments are grounded in God's action and the Incarnation, even when they employ philosophical distinctions.
Do not counter by claiming that all iconoclasts were Platonists or that all non-Orthodox Christians reject matter. Both sides in the Byzantine debates used inherited intellectual tools.
A resemblance does not prove borrowing, and borrowing alone does not prove either faithfulness or corruption. Establish chronology and changed meaning before making a historical claim.
