Saint Peter's Praesidium was formed in the 1950s and was active until at least
1976. It was reformed on 7 March 2007. Meetings are held in the Parish Centre
every Tuesday at 11.00 am. The photograph on the right shows members of the Legion
of Mary carrying a statue of Our Lady in procession through the Church grounds
in May in the late 1950s.
In 2009, the Parish hosted a Peregrinatio Pro Christo - Journeying for Christ. A team of Legionaries from Ireland, shown below, came to Ardrossan on 4 July and were introduced to the congregation during Masses that weekend. Starting on 6 July, they visited as many homes as they could, introducing themselves and briefly inviting people to attend their own Church, return to Church or to take up the habit of prayer. Accommodation was provided by Saint Peter's Parishioners who also served meals daily in the Parish Centre.
10 July, there was a special Mass to mark the end of the Peregrinatio Pro Christo.
This was followed by a social event in the Parish Centre. The Legionaries returned
home on 11 July.
