If you are not a member, you are not a part of. If you are not a member you cannot be inside. If you are separated from, you are not a member. If you are separated from, you cannot be a part of, or inside.
As Pius XII teaches,  "Actually only those are to be included as members of the Church who have [...] not been so unfortunate as to separate themselves from the unity of the Body..."

You are trying to make a distinction when there is none to be made

One who the Church Excommunicates is a separated member. You fail to make this distinction. 

The censure is lifted, the heretic is now a member again. The reason is evident. A non-member cannot partake in the sacraments.

Nope. You still don't have it. Tell that same thing to a heretic priest administering extreme unction.

I say: What do you make of those validly baptised as infants in heretical sects? They were made Catholic by their baptism, but adhere to their false sect when they reach the age of reason. Are they still Catholic?

You say: As St. Thomas said: "Baptism without faith is of no value." They are not members after the age of reason if they remain adhering to their false sect.

I say: Not members, okay. But I asked if they are Catholic. Are they?

You say: No, because they never were, as St. Thomas said: "Baptism without faith is of no value."

I say: Huh? You're saying infants validly baptised in heretical/schismatic sects are not Catholics?


You say: No, I never said that - you are falsely saying I said that

As they say: Make it make sense

As baptized infants they were Catholics until they attain the age of reason. Then they need to be raised in the faith in order to be Catholic. If they were never raised in the faith FROM THE AGE OF REASON, then never were Catholic - since the age of reason. That's what I meant. 
It should be obvious to you that baptized infants are Catholic but as infants, not obliged to have the faith. 
 

You're trying to make a distinction, with no conclusion and no facts.

You're arguing that Pius XII meant that OTHER sins are similar to heresy, schism or apostasy.  But he doesn't list those.  Nor does he make a reference to a list that exists.  Your distinction fails. 

You have no proof that this distinction is valid.  Making a distinction without an explanation is illogical.

PPXII said: "For not every sin." That is what he means. Live with it. It does not matter how badly you want what he said to mean "For no other sin," simply accept that he would have said that if that's what he meant.   

  There are various ways to write the same thing.  You're insane.  Go ask 10 other people what that ENTIRE sentence means, and get back to us.

I already know what it means, you should too. But don't ask 10 other people or you'll get 10 different answers LOL

"Separated member": Not actually a thing

What Pius XII taught: "Members"

What he didn't teach: "Separated members"

The only distinction to be made is between members and non-members. You are literally just making things up

Nope. You still don't have it. Tell that same thing to a heretic priest administering extreme unction.

Tell what? If I don't get it, please explain it to me..because I truly do not understand what you are trying to say

As baptized infants they were Catholics until they attain the age of reason. Then they need to be raised in the faith in order to be Catholic. If they were never raised in the faith FROM THE AGE OF REASON, then never were Catholic - since the age of reason. That's what I meant.

Okay, I agree. But I (understandably, I think) read "they never were" to simply mean "they never were"

"Separated member": Not actually a thing... You are literally just making things up

Yep.

He doesn't want to admit that heretics lose membership, so he keeps switching the argument from 'catholic' to 'member' and back again, to avoid the issue.
