Clearly that is untrue, since they can be separated in time and space and by what minister may administer them. The hyperbole is really quite unhelpful.
I am not sure about what you mean when you say "seperate in time and space".
We are subject to the baptism and what is derived from it which is the blessings of the church in the other 6 sacraments.
I am aware that some "ministers" pick and choose from the sacraments and applies them as they deem fit. But I am not speaking of this kind of minister.
The Holy Church is not the subject of a minister. The Holy Church keeps all 7 sacraments as supreme right of the faithful.
The Church cannot provide matrimony to a person who wants to maintain or receive the sacrament outside church doctrine even if that person has had a correct baptism. Some ministers may oblige the person but the action is highly questionable.
Orthodoxy is not questionable.
