Pentecost - All Saints Sunday
The Holy Spirit and the relics of the Saints
Before baptism, one is called the “old man”, but after baptism the “new man”. Now the Holy Spirit is the abiding Soul of the “new man”, and Ηe remains, not only during the body’s life, but also after its death, and in the case of the saints Ηe performs miracles and works signs. For the bones of the just, that is to say, [the relics] of the apostles and martyrs and all the saints, while they do not have any natural soul in them – for that left them at their death – still have the Holy Spirit abiding with and in them, and it is He who effects signs and wonders in them; and demonic spirits cry out bitterly at his power within them, for sicknesses are driven off and illnesses chased away.
