Acts 2 says "your sons & daughters shall
prophesy, and also on bondslaves, both men & women.
Thayer's lexicon
to prophesy, i. e. to be a prophet, speak forth by divine inspiration; to predict (Herodotus, Pindar, Euripides, Plato, Plutarch, others);
a. universally,
Matthew 7:22.
b. with the idea of foretelling future events pertaining especially to the kingdom of God:
Matthew 11:13;
Acts 2:17, 18;
Acts 21:9; περί τίνος,
Matthew 15:7;
Mark 7:6;
1 Peter 1:10; ἐπί τίνι, over i. e. concerning one (see ἐπί, B. 2 f. β'., p. 234a),
Revelation 10:11; εἰς τινα (i. e. Christ), the Epistle of Barnabas 5, 6 [ET]; προφητεύειν followed by λέγων, with the words uttered by the prophet,
Jude 1:14; followed by ὅτι,
John 11:51.
c.
to utter forth, declare, a thing which can only be known by divine revelation:
Matthew 26:68;
Mark 14:65;
Luke 22:64, cf. 7:39;
John 4:19.
d.
to break forth under sudden impulse in lofty discourse or in praise of the divine counsels:
Luke 1:67;
Acts 19:6 (
1 Samuel 10:10, 11;
1 Samuel 19:20, 21, etc.); —
or, under the like prompting,
to teach, refute, reprove, admonish, comfort others (see προφήτης, II. 1 f.),
1 Corinthians 11:4, 5;
1 Corinthians 13:9;
1 Corinthians 14:1, 3, 4, 5, 24, 31, 39.
e.
to act as a prophet, discharge the prophetic office:
Revelation 11:3. (On the word see Trench, N. T. Synonyms, § vi.)
Now, why would I use these verses, to speak about women preachers? Because the OT prophets prophesied, preached , taught the people, reproved, & comforted just like this lexicon says.
Does that mean every man & woman in the church will do all these things? No, not necessarily. Only when the Holy Spirit prompts them to, and I for one will not try to determine what He wants us to do at any given time.
But since the OT had men & women prophets that told kings what God said & what they needed to do, I see no reason why men & women prophets can't do the same today, you know, under a better covenant established on better promises.
All this is ministry that edifies the body of Christ. Just because a particular denomination or 4 or 8 doesn't believe that anymore isn't my fault. The Bible says it, and anyone who doesn't believe what God's Word says is foolish at least & I'd be afraid to say at most.
Stating that 1/2 the church or so can't speak to the world about their salvation is something I'd be afraid to do, because only the Godhead has such authority.
You want to argue about somebody "usurping" authority, why not discuss why all these people saying women can't preach based on preconceived notions are usurping authority on Christ's church? How dare someone argue against God! How dare someone judge the servant of God! She will stand, for God is able to make her stand, with you or without you.
