Inspired by Pentecost - a comparative look at the work of the Holy Spirit...
Roman Catholic - ...to the Holy Ghost we attribute the operations of grace and the sanctification of souls, and in particular spiritual gifts and fruits, because He proceeds from the Father and the Son as Their mutual love and is called in Holy Writ the goodness and the charity of God. The gifts of the Holy Ghost are of two kinds: the first are specially intended for the sanctification of the person who receives them; the second, more properly called charismata, are extraordinary favours granted for the help of another, favours, too, which do not sanctify by themselves, and may even be separated from sanctifying grace. Those of the first class are accounted seven in number, as enumerated by Isaias (11:2-3), where the prophet sees and describes them in the Messias. They are the gifts of wisdom, understanding, counsel, fortitude, knowledge, piety (godliness), and fear of the Lord. - Catholic Encyclopedia
Anabaptist/Mennonite - ... The Holy Spirit in His relation to the believer effects regeneration, assures of salvation, guides into truth, activates the conscience, purifies the heart, comforts, produces love, and gives power and joy in service ... The Anabaptists never identified the Holy Spirit with reason, or with emotion, or with the conscience, resisting the positions of rationalism and mysticism, but declared the Holy Spirit to be objective reality, revealing Himself to the believer in the Gospel ... In His relation to the Scriptures, the Holy Spirit was not considered to be a separate and independent "inner light" or "inner Word" whose authority might contradict and supersede the "written Word" as spiritualists taught. Anabaptists held that the Holy Spirit as the true author of Scripture is also the true interpreter of Scripture who does not contradict Himself...Considering the disparate origins of the movement it is not surprising to note that there is not only one Anabaptist view of the Holy Spirit. However, on the main points there was remarkable agreement. Throughout Anabaptism there was a profound conviction that the Spirit was at the center of Christian experience enabling the follower of Christ to rise above legalism to the transforming life of joyful obedience... - Global Anabaptist Mennonite Encyclopedia Online
Pentecostal - The Holy Ghost is not a third person in the Godhead, but rather the Spirit of God (the Creator), the Spirit of the resurrected Christ. The Holy Ghost comes to dwell in the hearts and lives of everyone who believes and obeys the gospel, as the comforter, Sustainer, and keeper (John 14:16-26; Romans 8:9-11). - United Pentecostal Church International, Apostles' Doctrine

Assembly of God - All believers are entitled to and should ardently expect and earnestly seek the promise of the Father, the baptism in the Holy Spirit and fire, according to the command of our Lord Jesus Christ. This was the normal experience of all in the early Christian Church. With it comes the enduement of power for life and service, the bestowment of the gifts and their uses in the work of the ministry.... This experience is distinct from and subsequent to the experience of the new birth...With the baptism in the Holy Spirit come such experiences as: an overflowing fullness of the Spirit; a deepened reverence for God; an intensified consecration to God and dedication to His work; and a more active love for Christ, for His Word and for the lost...The baptism of believers in the Holy Spirit is witnessed by the initial physical sign of speaking with other tongues as the Spirit of God gives them utterance....The speaking in tongues in this instance is the same in essence as the gift of tongues, but is different in purpose and use...
Sanctification is an act of separation from that which is evil, and of dedication unto God. The Scriptures teach a life of "holiness without which no man shall see the Lord." By the power of the Holy Spirit we are able to obey the command: "Be ye holy, for I am holy." Sanctification is realized in the believer by recognizing his identification with Christ in His death and resurrection, and by the faith reckoning daily upon the fact of that union, and by offering every faculty continually to the dominion of the Holy Spirit. - General Council of Assemblies of God, Statement of Fundamental Truths
Baptist - We believe that the Holy Spirit has always been at work in the world, sharing in the work of creation, awakening faith in the remnant of God’s people, performing signs and
wonders, giving triumphs in battle, empowering the preaching of prophets and inspiring the writing of Scripture. Yet, when Christ had made atonement for sin, and ascended to the right hand of the Father, He inaugurated a new era of the Spirit by pouring out the promise of the Father on His Church. We believe that the newness of this era is marked by the unprecedented mission of the Spirit to glorify the crucified and risen Christ. This He does by giving the disciples of Jesus greater power to preach the gospel of the glory of Christ, by opening the hearts of hearers that they might see Christ and believe, by revealing the beauty of Christ in His Word and transforming His people from glory to glory, by manifesting Himself in spiritual gifts (being sovereignly free to dispense, as he wills, all the gifts of 1 Corinthians 12:8-10) for the upbuilding of the body of Christ and the confirmation of His Word, by calling all the nations into the sway of the gospel of Christ, and, in all this, thus fulfilling the New Covenant promise to create and preserve a purified people for the everlasting habitation of God. - Bethlehem Baptist Church, Elder Affirmation of Faith [a church in my area]
Candy (Non-denominational Fundamentalist) - When a person really gets saved/born again, then the very Holy Spirit of God Himself indwells that new creature in Christ. Suddenly this person is given gifts from the Holy Spirit. Often one of those gifts is the gift of discernment - to discern true evil from true good. - Keeping the Home, "Lord, Lord!" - Christians who aren't. What are you?
Via this comparison, it appears Candy's view of the work of the Holy Spirit is most closely aligned with that of the Pentecostals (although Candy does believe in the Trinity). She hasn't written very much regarding the work of the Spirit -- perhaps it is something she should read more about.
