How can I create run-time object references for objects of Office Object Model?

[swifty]

My problem is, that I don't know, how to create a reference at run-time to a word application object.
For example:

Dim myWordApp As Object
Set myWordApp = CreateObject("Word.Application")

Than I have a reference to a word application.
But, how can I check the value of myWordApp.Activedocument.Paragraphs(1).Alignment dynamically, if at compile-time I don't know yet, whose value I want to check, because it is generated from a string?
"Activedocument.Paragraphs(1).Alignment"
or
"ActiveDocument.Paragraphs(1).LineSpacing"
or
"ActiveDocument.CodeName"
