Arnold was born in Malta and is a big fan of the sea. Whilst studying philosophy, he frequented the University Chaplaincy, at the University of Malta, where he came to know the Jesuits, where he then went on to work for two years. After having offered and drank his fair share of cups of coffee (and ending up having to wash them after!), in 2014 he decided to become a Jesuit himself. At the moment he is studying psychology at the LUMSA University in Rome.
