“St Ambrose [teaches], Do not be afraid of giving the Lord what is yours, since He granted to you what is His (Treatise on the Gospel According to St Luke, Book 4, no 79). In becoming man, the Son of God has given to men the power to become sons of God (John 1:12) and to participate in the divine nature (2 Peter 1:4), in the divine life.” (Archbishop Dmitri (Royster), The Miracles of Christ, pg 52)
Last year (2009) at Christmas I ran a blog series, Twelve Quotes for Christmas, which had quotes from some Patristic Fathers and a few other Orthodox writers related to Christmas. Each quote was coupled with photos of creches that were on display at the Dayton Art Institute.
That series is now available as a PDF at https://frted.files.wordpress.com/2010/12/twelve-quotes-for-christmas.pdf
