Quis ut Deus?, a Latin sentence meaning "Who is like God?", is a literal translation of the name Michael (Hebrew: מִיכָאֵל‎, transliterated Micha'el or Mîkhā'ēl).

"Michael" appears as the name of several men in the Old Testament. In the Book of Daniel it is the name of the "prince" of the people of Israel. In the New Testament the name is given to an archangel in the Epistle of Jude 1:9 and, in the Book of Revelation 12:7, to the leader of angels who defeat "the dragon" and his fallen angels, a dragon identified in Revelation 12:9 as "that ancient serpent, who is called the devil and Satan, the deceiver of the whole world".

The sentence Quis ut Deus? is particularly associated with Archangel Michael. In art St. Michael is often represented as an angelic warrior, fully armed with helmet, sword, and shield, as he overcomes Satan, sometimes represented as a dragon and sometimes as a man-like figure. The shield at times bears the inscription: Quis ut Deus, the translation of the archangel's name, but capable also of being seen as his rhetorical and scornful question to Satan.

Brian Robert Doerksen (pronounced "durkson") is a Canadian Christian singer-songwriter and worship leader from Abbotsford, British Columbia born in 1965.

For many years Doerksen was part of the Vineyard Churches as well as Vineyard Music Group. In that context he has been extremely influential in the area of contemporary Christian worship music. He was a featured worship leader on many Vineyard worship CDs and has also taught extensively on worship leading and song writing. Brian's worship recordings are known for their high production values and quality songwriting.

Notable songs written by Doerksen include: "Refiner's Fire" (1990), "Faithful One", "Come Now is the Time to Worship" (1998), "Hope of the Nations," (2003), "Holy God", and "Today (As For Me and My House)".

More recently Brian Doerksen has been producing worship music through Integrity's Hosanna Music, including his albums You Shine (2002), Today (2004), Live In Europe (2005), Holy God (2006) and It's Time (2008).

Brian Doerksen received a Gospel Music Association Dove Award in 2003, only the second Canadian to be so honoured. He has also won a string of Covenant Awards during his career including four in 2005, among them: Artist of the Year, Praise And Worship Album Of The Year and Praise And Worship Song Of The Year. Three more Covenant Awards followed in 2006, and a further six in 2007. In 2008 he won a Juno Award for the album Holy God.

Deitrick Vaughn Haddon (born May 17, 1973) is a Gospel singer, songwriter, producer and pastor. A popular artist known for his contemporary style of music, he is well known for his progressive gospel styles.

Haddon is a native of Detroit, Michigan.

Haddon launched his solo career as a Christian R&B vocalist with the Lost & Found on Tyscot/Verity in 2002. The set peaked at #1 on Billboard's Top Gospel Charts and received wide critical acclaim and spawned the hit "Sinner's Prayer" which received heavy spins on gospel and mainstream R&B radio stations.

The 70's-leaning Crossroads followed in 2004, led off by the upbeat single "God Is Good". In an uncharacteristic move for marketing a gospel album, Detrick made an appearance on the long-running syndicated series Soul Train performing the single as well as the title track from the album.

Haddon appeared to be pushing his Gospel artistry for many things further into the ranks of mainstream venues with 7 Days, released October 10, 2006. 7 Days was executive produced and produced almost entirely by R&B stalwart producers Tim & Bob (also responsible for hits by Sisqo, Chante Moore, Karen Clark Sheard, and others). Balancing out the contemporary bulk of the album is the traditional gospel flavored lead single "Heaven Knows" which Deitrick produced himself.
