Your original claim: the RC Sacraments are not the same
as EO.
Did you read the USCCB link?
Can you show me how they are not the same?
Please skip the part about mystery as my answer
to that is clear: EO Sacraments are not " more mysterious"
by virtue of being called so
From the two links the difference may not be that clear, but neither of those articles were written for the purpose of differentiating themselves from the other group.
So in light of that what other differences are there?
The fact that one divines seven of them and one
doesn’t does not change the nature of the
Sacrament/Mystery does it?
The difference is likely to be found in the perception of the sacrament itself and the manner in which it works. There is a certain transactional and scientific quality that is present in Catholic sacramental theology whereby one receives a sacrament and the act of receiving the sacrament is the exact moment when the grace itself is given. Orthodoxy does not necessarily think in this fashion.
Orthodoxy does not feel the need or have the desire to explain how sacraments work the way Catholic theologians do. For example, there is a doctrine of the real presence in Orthodoxy, but not of transubstantiation for the simple reason that one cannot (or should not) explain one of the great mysteries of the faith. So when Catholics read some Orthodox writings on the Eucharist they may think “that’s what we believe,” but the Orthodox are much less likely (if at all) to read something on transubstantiation and think, “that’s what we believe.” From a Catholic perspective things look more similar because Catholics tend to have a mechanistic view of how sacraments work. So if criteria A, B, C, and D are met: it’s a sacrament, but if only B, C, and D are met: it’s valid but illicit, and on and on. Orthodoxy tends to have the simple position that if the Orthodox Church does it, then it’s a sacrament; if someone else does it, then it’s not relevant to them because they are not Orthodox.
The idea of numbering the mysteries or sacraments is a Western one. In John McGuckin’s book on Orthodoxy I believe he mentions that there is no real limit on the number mysteries, but there may be a system of ordering them into “major” or “minor” mysteries. But then I believe he goes on to say that even this distinction is arbitrary and reflects a Western need for ordering things.
You need to give me something substantial- for
instance is the Body of Christ and Blood of Christ
different in substance in the Eucharist?
Is the Baptism more/less cleansing?
What?
I believe I addressed this above; but to sum up: Catholic theology permits sacraments to be understood in a mechanistic, ordered fashion to a degree not acceptable in Orthodoxy. The difference is not so much in how Catholicism and Orthodoxy claim sacraments or mysteries to help the believer, but in how the sacraments or mysteries
themselves are said to function.
