II. What is This Sacrament Called?

From The Catechism of the Catholic Church

1329
The Lord’s Supper, because of its connection with the supper which the Lord
took with his disciples on the eve of his Passion and because it anticipates
the wedding feast of the Lamb in the heavenly Jerusalem.¹⁴¹
The Breaking of Bread, because Jesus used this rite, part of a Jewish meat when
as master of the table he blessed and distributed the bread,¹⁴² above
all at the Last Supper.¹⁴³ It is by this action that his disciples will
recognize him after his Resurrection,¹⁴⁴ and it is this expression that
the first Christians will use to designate their Eucharistic
assemblies;¹⁴⁵ by doing so they signified that all who eat the one
broken bread, Christ, enter into communion with him and form but one body in
him.¹⁴⁶
The Eucharistic assembly (synaxis), because the Eucharist is celebrated amid
the assembly of the faithful, the visible expression of the Church.¹⁴⁷
