Norton was born in Sydney in 1958 to Joseph and Dawn Norton (née Spillane). He has an older brother Chris and a younger sister, Julie. He attended Marist Brothers Eastwood, where the school's chaplain was a Divine Word Missionary who had previously lived in India for 30 years. He took a trip to India during his final year of high school, which he later said was influential in discerning his vocation.[1] After graduating, he commenced tertiary studies for a Bachelor of Applied Science in Physiotherapy at Cumberland College of Health Sciences, Sydney.[2] He worked as a physiotherapist and worked with young street people in Darlinghurst who were experiencing homelessness, addiction, and mental health issues.[3]
He entered the seminary when he was 25 and moved to Mexico to continue his studies at the age of 28.[3] In 1985, he entered the Society of the Divine Word and in 1990, professed his final vows.[4]
