1-е Коринфянам 14:15

What is it then?--What is my determination thereupon? and--rather as Greek, "but"; I will not only pray with my spirit, which (Co1 14:14) might leave the understanding unedified, BUT with the understanding also [ALFORD and ELLICOTT]. pray with the understanding also--and, by inference, I will keep silence altogether if I cannot pray with the understanding (so as to make myself understood by others). A prescient warning, mutatis mutandis, against the Roman and Greek practice of keeping liturgies in dead languages, which long since have become unintelligible to the masses; though their forefathers spoke them at a time when those liturgies were framed for general use.

The apostle here sums up the argument hitherto, and, I. Directs them how they should sing and pray in public (Co1 14:15): What is it then? I will pray with the spirit, and I will pray with the understanding also. I will sing with the spirit, etc. He does not forbid their praying or singing under a divine afflatus, or when they were inspired for this purpose, or had such a spiritual gift communicated to them; but he would have them perform both so as to be understood by others, that others might join with them. Note, Public worship should be performed so as to be understood. II. He enforces the argument with several reasons. 1. That otherwise the unlearned could not say Amen to their prayers or thanksgivings, could not join in the worship, for they did not understand it, Co1 14:16. He who fills up or occupies the place of the unlearned, that is, as the ancients interpret it, the body of the people, who, in most Christian assemblies, are illiterate; how should they say Amen to prayers in an unknown tongue? How should they declare their consent and concurrence? This is saying Amen, So be it. God grant the thing we have requested; or, We join in the confession that has been made of sin, and in the acknowledgment that has been made of divine mercies and favours. This is the import of saying Amen. All should say Amen inwardly; and it is not improper to testify this inward concurrence in public prayers and devotions, by an audible Amen. The ancient Christians said Amen aloud. Vide Just. Mart. apol. 2. prop fin. Now, how should the people say Amen to what they did not understand? Note, There can be no concurrence in those prayers that are not understood. The intention of public devotions is therefore entirely destroyed if they are performed in an unknown tongue. He who performs…

14:15-17 It is preferable both to worship in the spirit and to use words I understand in worship and ministry because public worship should always bless both God and others. Speaking in tongues without interpretation, though it gives glory to God and edification to the speaker (14:4), fails to benefit others who are present. • praise God along with you (literally say “amen” to your thanksgiving): Amen was the traditional congregational response to a prayer.
