Feast Day of St. Martin Luther King, Jr?

Um...not so fast. Fr. Z says:

"Holy Church does not permit Masses in honor of a dead person who isn’t a saint or blessed with an cult approved by Holy Catholic Church. It is not permitted to celebrate Mass on honor of a person who has no official cult. As a matter of fact most blesseds can’t even be honored at the altar unless there is permission given for that locale or institute."

"Masses for a dead person mustn’t be reduced to a “celebration of someone’s life”. That is not what Catholics do. During Mass we pray that God will be merciful to them."
