I am afraid not.

You're confusing the offering of grace from God in the theology of the sacraments with the history of the Church.

The community, for example, could not have a priest to "do this in anamnesis of Me" had Christ not instituted the Eucharist and ordained the apostles, which of course are "tenets" - the reality of the sacrament, the "creed" of ordination and consecration, and so on.

Yes, the sacraments are effective "ex opere operato", but that only establishes that we need to know how a sacrament is validly effected - tenet - before we can perform them.

We cannot even baptize without first knowing the formula - a creed or tenet.
