The Greek word used for 'thanks' is eucharistia. It is reflected in our word 'eucharist.' The word focuses on giving thanks for the death of Christ. Actually, the root word in the Greek is chair or char, which means 'joy.' Therefore 'thanks' is expressing joy because of a person, event or thing. Originally the word meant a thankful attitude. Later it came to mean the expression of thanks. It was commonly found in ancient inscriptions to pagan deities.
In the Septuagint Greek Old Testament the word had two basic references. First, it was used as an expression of thanks to God. Second, it spoke of someone giving thanks to someone else. The words, eucharistia (thanks) and eucharisto (to give thanks) appear 36 times in the epistles of Paul and 13 times in the Gospels. In the Gospels thanks is usually directed to God. A profound truth is hidden in this word 'thanksgiving.' In the Scriptures thanks is seldom given from one person to another person. Usually one person gives thanks to God for another person. Thus the glory and the thanks are due mainly to God, not the other people.
