[1] He adopted the Protestant doctrine, and fled to Antwerp where he met and assisted both William Tyndale and George Joye.
He was arrested in 1531 by Sir Thomas More;[3] after revealing the names of some of his Protestant colleagues he escaped in December of the same year, returning to Antwerp.
[4] After Norris's death, Constantine was made the vicar of Llawhaden in Pembrokeshire, but some unguarded remarks to John Barlow in 1539 led to his imprisonment by Thomas Cromwell in the Tower of London.
He became the registrar of St David's in Wales, then gained the position of royal visitor of the diocese in 1547, ascending to Archdeacon of Carmarthen and Prebendary of Llangammarch in 1549.
Although Constantine was stripped of his registrarship and livings during Mary's reign, he was back in favour by 1559 when he was appointed one of the visitors for the Western circuit of dioceses.
