noun
Christian term for the sacrament of the Lord's Supper. Often used in liturgical or theological contexts.
See also: 聖餐 (せいさん)
教会でユーカリストにあずかる。
I receive the Eucharist at church.
聖餐 is the native Japanese term for the Eucharist, used in similar contexts but with a more formal or traditional nuance.
Borrowed from English 'Eucharist', ultimately from Greek εὐχαριστία (eucharistia, 'thanksgiving').
