I’d like to talk about grace. Specifically, how grace is given and the mechanism for how it flows into the life of the believer.
I was a Protestant/Evangelical for a short time, but definitely not a theologian. So I might not represent the Protestant/Evangelical view on this point correctly. On the other hand, there may be multiple views since there isn’t one governing body among them to define orthodoxy on this point. Even so, I am open to being corrected.
It seems to me that under Protestant/Evangelical theology, there is no explicit “vehicle” to impart grace, no explicitly defined way that grace flows into the life of the believer. It is just sort of like an invisible cloud that somehow appears, surrounds, or is absorbed into the believer’s soul once faith in Christ is exercised. If faith in Christ ceases, the cloud departs. For those who believe in Once Saved, Always Saved (OSAS), the cloud never departs.
Protestants/Evangelicals reject the necessity of the sacraments. I have had the impression that they reject the physicality associated with the sacraments. They seem to recoil at the idea that God has instituted something physical as a way to channel grace into the life of the believer. To them, grace is only imparted in an unseen, spiritual manner, like an invisible cloud.
As I have mentioned before, I spent a lot of time in a gnostic cult, where we actually studied different gnostic texts by famous gnostic authors (such as G.I. Gurdjieff and his most famous disciple, P.D. Ouspensky). So I am very well acquainted with it. Gnosticism has two main ideas: 1) there is special, hidden knowledge which is only given to certain people, and this knowledge is what saves people. 2) the physical realm is undesirable, evil, and/or ultimately unnecessary. It needs to be shed and discarded the way a snake sheds and discards his skin.
Because of that experience, anytime I see people rejecting the physical, claiming it is unnecessary or bad, my alarm bells go off.
The Church does not teach that special knowledge saves people, and she teaches that the physical is good. So good, in fact, that our physical bodies will be resurrected. Because of this, the sacraments make sense to me precisely because they are physically based.
The Church teaches that the sacraments are the normative “vehicle” through which grace is given to Christians. This physicality speaks to the goodness of the physical creation, to Christ’s humanity and his physical body, to the idea that the physical is good, that God loves the physical, and he uses it for our good.
I take the physicality of the sacraments as evidence for the the Church’s claim about who she is, not as evidence against that claim.
Edited to add: this post is based on a comment I left on a blog called Orthodox Christian Theology.
