'Charismatics' believe in what is known as 'continuing revelation', i.e. the idea that their
'h-ly sp-rit' (so-called) continues to 'speak' to them and tell them things that they are not only bound to believe, but bound to tell others and relate as true. In short, the charismatic adherent acts as his/her own Magisterium, which is entirely Protestant and heretical in nature.
The charismatic movement was an offshoot of the 'holiness church' movement of the late 1800s and early 1900s in the US. The 'holiness church' was itself a result of the fracturing of the Methodist denomination into at least three distinct parts (Primitive Methodist, United Methodist and Holiness). The 'church of the Nazarene' is an offshoot of the 'holiness church'... what a zoo!
Anyway, the Methodists were schismatic from the Anglicans, who, of course, were schismatic from the Roman Catholic Church. The Methodists believed that Anglican 'worship' had become too rote, too mechanical, and that people were not being taught their 'faith' properly. Thus, the Methodists, like the Wesleys and George Whitefield (to a degree; he never actually left Anglican orders) began to insist upon 'methods' of encouraging worship and participation in parish life.
Once the Methodists reached the Colonies, they were met with resounding failure. It took decades for Methodism to take hold on a large scale in the U.S. Only Whitefield was successful at 'converting' anyone (indeed, thousands made 'professions of faith'; even Benjamin Franklin, known for his rationalist/agnostic stance, was suitably impressed), and it became, as with Jonathan Edwards, the Puritan, 'de rigeur' to get 'saved' or 'converted' at a Whitefield meeting.
Alas, as is always the case with start-up denominations, which were founded because someone disagreed with someone and started a 'new' thing that was supposed to 'restore' or 'return' people to the 'real doctrines of whatever', people got sick of the Methodists, too. They charged that the Methodist ministers and people were too routine, too formal and too mechanical. These dissenters insisted that the 'spirit' was still giving out gifts like tongues, prophecy, healing, etc, in their day, and began demanding that they be allowed to interrupt services with their ecstatic gobbledy-gook. Of course, the entrenched Methodist leadership wanted nothing to do with such carrying on, so the dissenters left and formed the 'holiness church', which was intended to bring 'christians' back to zeal for right living, ecstatic 'powers' of the 'spirit' and so on.
Within a generation or two of the creation of the holiness denomination, they had ALREADY split into several NEW denominations. THOSE denominations came about because a woman named Agnes Ozman supposedly received the 'gift of tongues' at a Bible-school class in the Midwest. Many people, disaffected by the routine and pomposity of the 'established' denominations, took to this 'new' phenomenon immediately. Fast-forward to 1906 and Azusa, California, and a BARN (of all places) on Azusa Street. There, a black man, not previously allowed to attend these new 'services', suddenly claims to be able to 'get the spirit' while sticking his head in a bread-box. He becomes the 'pastor' of this new meeting that takes place in this barn, and the newspapers of the period start referring to the meetings as an attempt at a 'new Pentecost'. Hence the name, Pentecostal or Pentecostalism (for the movement).
Charismatic 'theology' is erroneous because it teaches that spiritual gifts like tongues have continued past the death of the Apostles; this cannot be true, because the spiritual gifts in question were given to Christians IN ORDER to authenticate the message of Christ that they were preaching; Apostolic authority was then necessary to examine any converts and CONFIRM them in the Faith. Once Christian communities were established, with duly appointed Bishops, priests and deacons, the CHURCH rather than the individual, became the repository of the 'spiritual gifts'.
In other words, charismatic gifts were necessarily MISSIONARY, designed to be proof that their bearer was in fact an emissary of Christ. There always was, however, and always needed to be, a hierarchy of gifts, from the least necessary for spiritual growth to the most necessary. Tongues were among the least gifts; once native-speaking Christians were confirmed in newly-reached lands, there was no further need to use tongues in those areas. Preaching, on the other hand, was considered a FAR more important gift, because spiritual formation is the ongoing process whereby our lives are made conformable to Christ, and spiritual fathers (priests and Bishops) are always necessary for that formation.
Charity (1st Epistle of St. Paul to the Corinthians, chapter 13) is considered the GREATEST of the gifts that still abide in EVERY Christian (it is clear from the Biblical text that not every gift would exist indefinitely in every Christian). Of 'faith, hope and charity', the greatest is charity, because faith can be had individually, even when living as a hermit. Hope is greater, because hope takes faith and OFFERS it to the world and helps one to SEE the world as redeemable in Christ. Charity, however, is the greatest gift because Charity represents the totally selfless giving to others, despite hardships, despite rejection, that was the hallmark of Christ's ministry on earth before the Cross.
Charismatic beliefs put the individual, rather than the Church, at the top of the ladder of authority. They likewise insist that FAR LESSER gifts be given equal place with the GREATEST gifts, which are defined DE FIDE by the Apostle Paul.
Charismaticism is also the bastard baby of Protestant self-determinism, and thus is to be rejected, not just avoided or qualified with platitudes about 'but they believe such nice things'.
Charismatic behaviors and beliefs are found, supported and encouraged NOWHERE in Tradition; said behaviors and beliefs are actually solemnly condemned in many places in the Councils of the Church.
Forgive me for not going into how the Charismatic movement reached into the Novus Ordo, but the NO blasphemes Christ and denigrates His Sacrifice ENOUGH without me rehashing the awful sacrileges that take place in Novus 'charismatic' services.
Holy Apostles, filled with the Holy Spirit's power to build the Church, pray for us.
Sacred Heart of Jesus, have mercy on us.
