Mary of Galilee, the First Disciple Church at the corner of Quinliven and How Roads, Aldinga was opened in March, 2009.

Galilee has a very amicable sharing arrangement with the Aldinga Lutheran Community and is situated on the grounds of the new Galilee Learning Centre, which currently caters for primary-aged children.

The Aldinga Catholic community began to celebrate Mass in the Butterworth Road kindergarten in the early 1980s, with parishioners seated on kindy chairs.

Building of the first Galilee Church on Quinliven Road, Aldinga Beach commenced on 1 September, 1984. It was originally built by the Lutheran community of Aldinga / Port Willunga and opened on 20 January, 1985 by Dr C I Koch. The Catholic community accepted an invitation from the Lutheran community to use the Galilee Church and Mass was celebrated there from the late 1980s to 2006.

Early in 2002 negotiations began ot purchase the building, as it was becoming a financial burden to the owners. The Church was transferred to the Willunga Catholic Parish on October 1, 2002. It was dedicated by Archbishop Philip Wilson on 17 April, 2004. The Lutheran community continued to share the building as they do Galilee space to this day.

When dedicated the Church was renamed Mary of Galilee, the First Disciple. Parishioners were asked for suggestions for the name, with most being clear that 'Galilee' remain in the title in respect for the connection with the Lutheran community
and the characteristics of the area.
