The lunette resembles another liturgical object, the pyx or carrying case, but their functions are distinct; the pyx serves to transport the Host outside the church in order to take communion to an alternate venue, while the lunette remains within the church and serves to display the Host to onlookers.
All of these objects, whenever they contain a consecrated host, are normally kept within the church tabernacle when they are not in use. The tabernacle may be behind the main altar, at a side altar, or within a special Eucharistic chapel.
