I guess you meant unrependent sin, didn't you? We are all in a state of sin.
I'm not sure where you are coming from.
Catholics conscious of unconfessed mortal sin are not to take communion. It was this "State of sin" that I refer to.
I would not, in general, say we are all in a state of sin. We are born that way, but we have the sacraments to alter this.
