The act of allowing people to know about ones’ fasting for the purpose of exhorting others to participate is one aspect of Scriptural fasting
You cannot base a doctrine on one scripture.
There are many times throughout the bible that the people of God fasted publicly. These acts were both pre and post Matthew 6:16, as we will see.
Public known fasts pre Matthew 6:16: (Nothing secretive about these fasts by God’s people)
2Ch 20:1 It came to pass after this also, that the children of Moab, and the children of Ammon, and with them other beside the Ammonites, came against Jehoshaphat to battle.
2Ch 20:2 Then there came some that told Jehoshaphat, saying, There cometh a great multitude against thee from beyond the sea on this side Syria; and, behold, they be in Hazazontamar, which is Engedi.
2Ch 20:3 And Jehoshaphat feared, and set himself to seek the LORD, and proclaimed a fast throughout all Judah.
Ezr 8:21 Then I proclaimed a fast there, at the river of Ahava, that we might afflict ourselves before our God, to seek of him a right way for us, and for our little ones, and for all our substance.
Est 4:15 Then Esther bade them return Mordecai this answer,
Est 4:16 Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in unto the king, which is not according to the law: and if I perish, I perish.
Est 4:17 So Mordecai went his way, and did according to all that Esther had commanded him.
Est 4:15 Then Esther bade them return Mordecai this answer,
Est 4:16 Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in unto the king, which is not according to the law: and if I perish, I perish.
Est 4:17 So Mordecai went his way, and did according to all that Esther had commanded him.
Psa 35:13 But as for me, when they were sick, my clothing was sackcloth: I humbled my soul with fasting; and my prayer returned into mine own bosom.
Joe 1:14 Sanctify ye a fast, call a solemn assembly, gather the elders and all the inhabitants of the land into the house of the LORD your God, and cry unto the LORD,
Joe 2:15 Blow the trumpet in Zion, sanctify a fast, call a solemn assembly:
Jon 3:5 So the people of Nineveh believed God, and proclaimed a fast, and put on sackcloth, from the greatest of them even to the least of them.
Zec 8:19 Thus saith the LORD of hosts; The fast of the fourth month, and the fast of the fifth, and the fast of the seventh, and the fast of the tenth, shall be to the house of Judah joy and gladness, and cheerful feasts; therefore love the truth and peace.
Publicly known fasts-post Matthew 6:16: (Nothing secretive about these fasts by God’s people)
Act 13:1 Now there were in the church that was at Antioch certain prophets and teachers; as Barnabas, and Simeon that was called Niger, and Lucius of Cyrene, and Manaen, which had been brought up with Herod the tetrarch, and Saul.
Act 13:2 As they ministered to the Lord, and fasted, the Holy Ghost said, Separate me Barnabas and Saul for the work whereunto I have called them.
Act 13:3 And when they had fasted and prayed, and laid their hands on them, they sent them away.
Act 14:21 And when they had preached the gospel to that city, and had taught many, they returned again to Lystra, and to Iconium, and Antioch,
Act 14:22 Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God.
Act 14:23 And when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed.
2Co 6:1 We then, as workers together with him, beseech you also that ye receive not the grace of God in vain.
2Co 6:2 (For he saith, I have heard thee in a time accepted, and in the day of salvation have I succoured thee: behold, now is the accepted time; behold, now is the day of salvation.)
2Co 6:3 Giving no offence in any thing, that the ministry be not blamed:
2Co 6:4 But in all things approving ourselves as the ministers of God, in much patience, in afflictions, in necessities, in distresses,
2Co 6:5 In stripes, in imprisonments, in tumults, in labours, in watchings, in fastings;
2Co 6:6 By pureness, by knowledge, by longsuffering, by kindness, by the Holy Ghost, by love unfeigned,
2Co 6:7 By the word of truth, by the power of God, by the armour of righteousness on the right hand and on the left,
2Co 6:8 By honour and dishonour, by evil report and good report: as deceivers, and yet true;
2Co 6:9 As unknown, and yet well known; as dying, and, behold, we live; as chastened, and not killed;
2Co 6:10 As sorrowful, yet alway rejoicing; as poor, yet making many rich; as having nothing, and yet possessing all things.
2Co 11:24 Of the Jews five times received I forty stripes save one.
2Co 11:25 Thrice was I beaten with rods, once was I stoned, thrice I suffered shipwreck, a night and a day I have been in the deep;
2Co 11:26 In journeyings often, in perils of waters, in perils of robbers, in perils by mine own countrymen, in perils by the heathen, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren;
2Co 11:27 In weariness and painfulness, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness.
I submit that the scripture Matthew was about a heart attitude. Jesus was calling His disciples to “Be not like the hypocrites.”
If you take this scripture as the only authority about fasting then you have to do likewise about praying. The scripture states in the exact same context:
Mat 6:6 But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
This kind of reasoning would discourage anyone from praying publicly!
