[Non-Sequitur]

Congress has the control to define purview and even set terms of federal judges including the supreme Court.

Define purview for lower courts, yes. But terms are defined by the Constitution, as is the jurisdiction of the Supreme Court. Congress cannot overrule that.

[Fledermaus]

Again, not according to this sentence: In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make.
