From Light and Life Publishing, to help balance sermon/homily offerings:
Alexander Schmemann: Celebration of Faith Sermons
Chrysostom: Eight Sermons on the Book of Genesis
Gregory Palamas: Mary the Mother of God; On the Saints; The Saving Work of Christ
Seraphim Sigris: The Rainbow Sermon
Michael Lightfoot: Sermons for the Orthodox Liturgical Year
Anthony M. Coniaris: Sermons on the Major Holy Days of the Orthodox Church
Note: Palamas is a figure of the stature of Augustine or Aquinas. It's unfortunate that Logos carries none of his works.
