I was expecting this @Edward429451 but…
Your argument depends on treating “when” as a command, but that is not how the Greek construction works in this passage.
In all three cases
almsgiving
prayer
fasting
…the same grammatical form is used:
Ὅταν + subjunctive verb
This construction means “whenever” or “when it happens”, not an imperative command.
So the structure is:
not “you must do this”
but “whenever you do this, do not do it like the hypocrites”
That applies equally to all three. The passage is regulating manner, not establishing obligation.
Now the key issue.
You are correct that almsgiving and prayer are expected practices across Scripture. That expectation, however, does not come from Matthew 6 itself, but from the broader canonical witness.
For example:
Prayer is explicitly commanded elsewhere
~1 Thessalonians 5:17
“pray without ceasing”
Giving is explicitly commanded elsewhere
~2 Corinthians 9:7
“Each one must give as he has decided in his heart”
Now apply the same test to fasting.
Where is the New Testament command that says believers must fast?
It is not present.
There is no imperative verb anywhere in the apostolic writings commanding fasting as a standing obligation.
So you cannot import obligation into Matthew 6 when the rest of the New Testament does not establish it.
What Matthew 6 is actually doing is very precise.
It assumes three known religious practices and corrects hypocrisy in them.
The repeated pattern is:
do not practice before men.
practice in secret before the Father.
That is the controlling theme of the entire section.
It is about motive and visibility, not about instituting disciplines.
Now notice something important.
If your logic is followed consistently, then all three must carry equal legal force.
But even then, the passage still does not command them. It only regulates them.
So the argument becomes circular:
You are reading obligation into the word “when,” rather than deriving it from the grammar.
Finally, the broader New Covenant framework must govern interpretation.
In ~Colossians 2:16:
“Let no one pass judgment on you in questions of food and drink”
Fasting falls into that category of food abstinence.
If it were a binding command, Paul could not speak this way.
So…
Matthew 6 does not command fasting.
It assumes the possibility of fasting and corrects the way it is done.
Prayer and giving are commanded elsewhere in Scripture.
Fasting is not.
So the text cannot be used to make fasting a requirement for believers.
Correct?
