Indeed, it is commanded that it be included in church services. 1 Cor 14:37 is the concluding commandment (of the Lord) for what is to be included in a church service (26-36). Let those who nullify the New Testament commands of God, do so at their own risk.
Then how is it, brothers? When you come together, each one of you has a psalm, has a teaching, has a tongue, has a revelation, has an interpretation. Let all things be for building up. If one speaks in a language, let it be by two, or at the most three, and in succession. And let one interpret. But if there is no interpreter, let him be silent in a church; and let him speak to himself and to God. And if there are two or three prophets, let them speak, and let the others judge. If a revelation is revealed to another sitting by, let the first be silent. For you may all prophesy one by one, so that all may learn and all may be comforted. And the spirits of the prophets are subject to the prophets. For God is not the author of confusion, but of peace, as in all churches of the saints. Let your women be silent in the churches; for it is not permitted to them to speak, but to be in subjection, as the Law also says. And if they desire to learn anything, let them ask their husbands at home; for it is a shame for a woman to speak in a church. Or did the Word of God go out from you? Or did it reach only to you? If anyone thinks to be a prophet, or a spiritual one, let him recognize the things I write to you, that they are a commandment of the Lord.
(1Co 14:26-37)
