"All Christians believe in Christ" is what I said (All A are B). From this does NOT follow, unlike your assumption, that "all believers in Christ are Christians" (All B are A). You interpreted my "All Christians believe in Christ" to also mean that "All believers in Christ are Christians" when you said that Muslims believe in Christ, too. Very basic logical rule, very grave assault on it... Tsk tsk...
Lesson 2:
For a statement of the form "All A are B" to be true, ALL instances of A have to be B. If only one single A is NOT B, the "All A are B" statement becomes false.
When you say that "all christian churches consider them selves part of the holy catholic church", you make the mistake of generalization. All it takes to debunk that statement is ONE christian church that does NOT consider itself part of the holy catholic church, and your statement is false. Come drive around in some Southern US states, and you'll see the freakiest christian churches. All are (or claim to be, at least) hardcore christian, but I wouldn't dare ask them if they're catholic...
