In the Orthodox Church, when we celebrate a feast commemorating an event in our salvation history, such as Pentecost, also known as Holy Trinity Sunday, it is followed directly by another feast honoring a person who figures heavily in the previous day’s event. In the present case, tomorrow is Holy Spirit Day. It seems a good time to post these thoughts from Metropolitan Anthony:
When we say that God is spirit, we say simply that he is not matter as we know it, that he is something quite different. In that sense it is a negative description that belongs already without the word, to that form of theology which is negative theology, apophatic theology, a theology of paradoxes, a theology that uses words to point toward the ineffable — that which can neither be described nor put into words and yet which must be indicated somehow in speech.
One could avoid speech. In Siberia there were pagan tribes that had deliberately rejected every human word for God. And when in conversation they wanted to indicate God they raised their hand towards heaven. This is possible in a civilization of direct communication by speech. It is no longer possible in a civilization of books. But whatever words we use we have got to be aware of the fact that we are not describing, we are not defining what God is, because the very thing we know about God is that he is beyond defining, beyond describing. So that when we say of God that he is a Spirit, when we speak of the Holy Spirit in particular, we do not mean to give a concrete definition or any description of what he is. We point towards the fact that he is beyond our conceptual knowledge, beyond every formulation, that is is what we don’t know, and this is what we mean to say by saying that he is a spirit as contrasted with us.
