St Therese of Lisieux, known as "the little flower", was only 15 when she entered the enclosed Carmelite religious order, seeking the Pope's special permission to do so at such a young age.

She died with tuberculosis aged just 24.

Despite her short life, Pope John Paul II declared St. Thérèse a Doctor of the Church just 28 years after her death in tribute to the way she inspired others.

St Therese, in a biography shared by Catholic Mission who are organising the pilgrimage of the relics, lived a simple life of prayer.

She taught that trust, especially trust in God, is a child-like virtue and that God is in the simple details of life.

She called it "her little way".

Father Brian Lucas from Catholic Mission hopes the relics' four-month journey around the nation will be an opportunity for Catholic people to gather - as they did when St Therese's relics were last brought to Australia 18 years ago.

"Catholic Mission hopes there is an opportunity for many Catholic people to find, in the life of St Therese and her parents Louis and Zelie Martin, an inspiration to give them comfort and security in times ahead," Fr Lucas said in announcing the pilgrimage.

"Her message for the world is that God is love."

The canonisation of her parents, he added, recognises the significance of family life.

"I would encourage local communities to come together for prayer," Fr Lucas said.

The relics of Saint Thérése of Lisieux and her parents Saints Louis and Zélie Martin will be at St Laurence's Catholic Church on February 27.

Bishop Columba will welcome the relics at 9.30am, and celebrate a Solemn Mass at 9.45am.

The church will be open from 11am for private prayer.

The Bishop will speak on the life on St Therese at 6.30pm, with another opportunity for private prayer until 8.30pm.
