On the day of 26 August
The commemoration of Saint Melchizedek, king of Salem and priest of God Most High, who greeted Abraham upon his return from victory, blessing him, offering a holy sacrifice, a spotless victim to the Lord; and, although without offspring, is recognized as king of peace and justice, and as priest forever in prefiguration of Christ.

Melchizedek is from the Old Testament and is not given the title of saint nor does he have a feast day.
Melchizedek was an Old Testament personage whose very existence is now questioned. He is not considered as a saint as that term is generally reserved for those who entered Heaven under the New Covenant of Our Lord.
Melchizedek is not a personal name but a title or role in the Bible, meaning "king of righteousness." There is no modern name associated with Melchizedek as he is a historical and biblical figure.
All of the twelve apostles were ordained by Christ to what is called The Higher Priesthood, sometimes known the Melchizedek Priesthood after the righteous King Melchizedek. He was the same king who Abraham paid tithes to.
The bible does not tell us what happened to Melchizedek.
No Melchizedek did not receive a tithe from David.
There is no Saint Patrick27 Day.
KJV does not say the Melchizedek wrote the psalm110, Psalm 110. 4 refers to Melchizedek as to being a priest forever. Melchizedek did not write anything in the bible, the bible refers to Melchizedek as a type order of priest that has always existed, meaning he is a theophany of Christ (manifestation)
A saint's feast day is a day we remember a particular saint and the life he or she led.
It is Saint Patrick's Day, not Saint Patties Day.
Melchizedek is not often mentioned in the Bible. All that can be surmised is that he was a priest and the king of Salem.
You have it backwards. Saint Patrick's Day was named after Saint Patrick. March 15 is the Catholic feast day of Saint Patrick.
No, Saint Patrick's Day is not Mother's Day. Saint Patrick's Day and Mother's Day are two way different holidays.
