What “heresy” would that be?

The Russian position (as described in the article) seems to me shot through with problems. First of all, the Rublev ikon *is still a bodily representation of God the Father*. Cloaking it in angelic garb does not change that.

Second of all, though yes, the full bodily representation of the Father is a quite late artistic development, the “Hand of God” motif for the Father is present from earliest Christianity and even Judaism from the Dura-Europos synagogue to today (my Jewish in-laws have it in their house).

"What “heresy” would that be?" A fundamental denial of the truth that the Father is ΅Ο ΩΝ", the Being Which created beingness. The Rublev icon does not purport to depict the Father (or the Son or the Holy Spirit for that matter), rather it is a depiction of an ancient scriptural pre-figuring of the Trinity.
