In case you were wondering, those baptised in other churches
need not be baptised again. This is of course subjected to a number
of factors not limited to,
1) The formula used (I baptise you in the name of the Father, and
of the Son, and of the Holy Spirit)
2) The intention (whether one is willing to be baptised in the
first place.)
Of course, sometimes there are grey areas, hence a need for an
interview by the parish priest.
Nah, Cardinal Newman wasn't baptised again. He just made a
statement of loyalty, that's all.
