Hi Mary-Anne,
In England and other English-speaking countries such as Australia, Canada and New Zealand, a marriage can take place in a church with a priest or pastor as the legal marriage celebrant.
In the Netherlands, civil registration is only possible for the registrar of BMD [de ambtenaar van de burgelijke stand ] and marriage in 1945 -1946 usually took place in the city hall. The marriage was - if one was a Catholic and certainly still in those years - later on consecrated in the church. In your example in the St. Jozef parish church in Deurne. Possibly the bride or groom lived in that parish? This was then written in the marriage register of this parish church. Note: sometimes there may be a time lag between the legal marriage and the church celebration. The church wedding may have been on the same day as the legal marriage, ...or weeks or even months later.
The parish records may still be in the parish archive or perhaps transferred to a central place or the episcopal archive?
Permission for consultation will have to be requested as a parish archive is not public within the meaning of the law.
For civil registration documents (after 1811- ) for the municipality Deurne see:

Church registration: due to the merger of the different parishes in the municipality of Deurne, there is now one large parish in Deurne >>> Sint Willibrord in Deurne, of which Rev. Father Paul Janssen is the parish priest.
