Paraclete comes from the Koine Greek word παράκλητος (paráklētos, that can signify "one who consoles or comforts, one who encourages or uplifts; hence refreshes, and/or one who intercedes on our behalf as an advocate in court"). The word for "Paraclete" is passive in form, and etymologically (originally) signified "called to one's side". The active form of the word, parakletor, is not found in the New Testament but is found in Septuagint in Job 16:2 in the plural, and means "comforters", in the saying of Job regarding the "miserable comforters" who failed to rekindle his spirit in his time of distress.
In Classical Greek
The term is not common in non-Jewish texts. The best known use is by Demosthenes:
Citizens of Athens, I do not doubt that you are all pretty well aware that this trial has been the center of keen partisanship and active canvassing, for you saw the people who were accosting and annoying you just now at the casting of lots.1 But I have to make a request which ought to be granted without asking, that you will all give less weight to private entreaty or personal influence than to the spirit of justice and to the oath which you severally swore when you entered that box. You will reflect that justice and the oath concern yourselves and the commonwealth, whereas the importunity and party spirit of advocates serve the end of those private ambitions which you are convened by the laws to thwart, not to encourage for the advantage of evil-doers. (Demosthenes On the False Embassy 19:1)
In the Greek New Testament the word is most prominent in the Johannine writings. It appears in the Gospel of John (14:16, 14:26, 15:26, 16:7) where it may be translated into English as "counselor", "helper", encourager, advocate, or "comforter". The early church identified the Paraclete as the Holy Spirit (Acts 1:5,1:8,2:4,2:38) and in the Gospel of Matthew, chapter 5 v. 4 Jesus Christ uses the verb παρακληθήσονται, paraclethesontai, traditionally interpreted to signify "to be refreshed, encouraged, or comforted". The text may also be translated as vocative as well as the traditional nominative. Then the meaning of 'paraclethesontai', also informative of the meaning of the name, or noun Paraclete, implicates 'are going to summon' or 'will be breaking off'... The Paraclete may thus mean 'the summoner' or 'the one, who, or that which makes free'
In 1 John 2:1 "Paraclete" is used to describe the intercessory role of Jesus Christ who pleads to The Father on our behalf. And in John 14:16 Jesus says "another Paraclete" will come to help his disciples, implying Jesus is the first and primary Paraclete.
In Matt 3:10-12 and Luke 3:9-17John the Baptist says a powerful one coming after him "will baptize you with the Holy Spirit and with fire. His winnowing fork is in his hand, and he will clear his threshing floor, gathering his wheat into the barn and burning up the chaff with unquenchable fire." (NIV)
Verses like these are often used by Christians in Trinitarian theology to describe how God is revealed to the world and God's role in salvation. According to Trinitarian doctrine, the Paraclete or Holy Spirit is the third person of the Trinity who among other things provides guidance, consolation, strength, and support to people. Other titles for the Holy Spirit include 'Spirit of Truth', Lightful Spirit of God Almighty, Holy Breath, Almighty Breath, Giver of Life, Lord of Grace, Helper, 'Comforter', 'Counselor' and 'Supporter'.
During his period as a hermit in the mid 12th century, Peter Abelard dedicated his chapel to the Paraclete because "I had come there as a fugitive and, in the depths of my despair, was granted some comfort by the grace of God.
The invisible presence of Jesus
Raymond Brown (1970) supported by Johnston (2005) read that the "another Paraclete" of John 14:16 is in many ways "another Jesus," the Paraclete is the presence of Jesus after Jesus ascends to his Father.
Many Muslim writers have argued that “another Paraclete” (John 14:16)—the first being Jesus—refers to Muhammad. The earliest scholar is probably Ibn Ishaq (died 767), who Islamic tradition states was the grandson of a Christian. Others who interpreted the paraclete as a reference to Muhammad include Ibn Taymiyyah, Ibn Kathir, Al-Qurtubi, Rahmatullah Kairanawi (1818-1891), and contemporary Muslim scholars such as Martin Lings. A few Muslim commentators, such as David Benjamin Keldani (1928), have argued that the original Greek word used was periklytos, meaning famed, illustrious, or praiseworthy, rendered in Arabic as Ahmad, and that this was substituted by Christians with parakletos.
