Spiritism is a very grave danger to man, and an abomination to the Lord. It is a very wicked sin. Certainly, all Christians in particular should firmly avoid even the appearance of such an evil! See I Thess. 5:22-23.
Classic-Pentecostal misuse of I Cor. 14:13-14 untenable
The two consecutive verses I Cor. 14:13-14 make both the Classic-Pentecostal view as well as the Neo- Pentecostal view of Paul’s teaching quite untenable. The two verses must, of course, be read together. For they are linked to one another (at the beginning of verse 14) by the conjunction “for” (or gar).
Now the two verses cannot mean what the Classic-Pentecostalists suggest they. They say the verses mean: ‘Let him who speaks in tongues in public, pray that someone else there present, should try to explain those utterances. For the tongues-speaker himself does not then understanding what the Holy Spirit is then praying through him.’
