I am using sacrament in the same way as you. For example, LG 11 describes ordination:

Those of the faithful who are consecrated by Holy Orders are appointed to feed the Church in Christ's name with the word and the grace of God. LG 11

The preaching of the Apostles is parallel to feeding with "the grace of God" which I assume means administering the 7 sacraments. The bishop preaching is a sign of  God speaking to us.  The hierarchy all flows from Christ, through the disciples, to us as it says in LG 5.

I see this as an explanation of the sacraments being instituted by Christ, and not terribly controversial. I cannot see where you get the idea that tenets and creeds precede the sacraments.
