Schismatic ? No. He is Eastern Rite Catholic.
(1) He celebrates Mass in Latin, so by definition he is not an Eastern Rite Catholic regardless of his birthplace or native tongue.
(2) The article clearly states that he was suspended by his bishop in 2001 and that he personally purchased and runs his church, not the diocese.
He's a schismatic.
Yes, he is Eastern Rite but the article makes it sound like he fought with his Bishop, who suspended him and then he went and bought a church. It makes it sound like he is operating without the approval of Rome. If that is the case, he is a schismatic.
