It does not need to be in the written word (Scripture). This teaching of Jesus has been handed down in his church's oral tradition for 2000 years.
2 Thessalonians 2:15
So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.
1 Corinthians 11:2
I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you.
2 Thessalonians 3:6 Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from any brother who is living in idleness and not in accord with the tradition that you received from us.
Mans traditions were never meant to replace God’s commandments. Jesus could not have been more clear about this point. He condemned this teaching. Not sure why anyone would use this arguements against one of God’s commandments.
Mark 7:7
And in vain they worship Me,
Teaching as doctrines the commandments of men.’
8 For laying aside the commandment of God, you hold the tradition of men—[
d]the washing of pitchers and cups, and many other such things you do.”
9 He said to them, “
All too well you [
e]reject the commandment of God, that you may keep your tradition.
Jesus teaches this path leads one to a ditch
Mat 15:3
He answered and said to them, “Why do you also transgress the commandment of God because of your tradition? 4 For God commanded, saying,
‘Honor your father and your mother’; and, ‘He who curses father or mother, let him be put to death.’ 5 But you say, ‘Whoever says to his father or mother, “Whatever profit you might have received from me
is a gift
to God”— 6 then he need not honor his father [
a]or mother.’
Thus you have made the [b]commandment of God of no effect by your tradition. 7 Hypocrites! Well did Isaiah prophesy about you, saying:
8
‘These people [c]draw near to Me with their mouth,
And honor Me with their lips,
But their heart is far from Me.
9 And in vain they worship Me,
Teaching as doctrines the commandments of men.’ ”
10 When He had called the multitude to
Himself, He said to them, “Hear and understand: 11 Not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man.”
12 Then His disciples came and said to Him, “Do You know that the Pharisees were offended when they heard this saying?”
13 But He answered and said, “Every plant which My heavenly Father has not planted will be uprooted. 14 Let them alone.
They are blind leaders of the blind. And if the blind leads the blind, both will fall into a ditch.”
2 Thessalonians 2:15
So then, brethren, stand firm and
hold to the traditions which you were taught by us,
either by word of mouth or by letter.
This translation is adding to God's Word. It does not say word of mouth. Its saying to follow what is taught by word (God's word) or
our letters (God's Word) not following man-made ideas especially over God's commandments. We are clearly told going outside of God's word is danger Isa8:20
Therefore,
G686 G3767 brethren,
G80 stand fast,
G4739 and
G2532 hold
G2902 the
G3588 traditions
G3862 which
G3739 ye have been taught,
G1321 whether
G1535 by
G1223 word,
G3056 or
G1535 our
G2257 epistle.
G1992
Sunday was commonly called the Lord's Day by the Christians who lived in the first century AD.
Not according to the words of God. Does man know more than God? God claimed His holy day, both written and spoken, There is no other only a counterfeit that competes with God’s Truth.
Exo 20:10 but
the seventh day is the Sabbath of the Lord your God.
Isa 58:13 “If you turn away your foot from
the Sabbath,
From doing your pleasure on
My holy day,
And call
the Sabbath a delight,
The holy day of the Lord honorable,
And shall honor Him, not doing your own ways,
Nor finding your own pleasure,
Nor speaking
your own words,
Mar 2:28 Therefore the
Son of Man is also Lord of the Sabbath.”
The seventh day is the Sabbath of the Lord and Jesus is Lord of the Sabbath as it is THE holy day of the Lord thy God, meaning there is only one, the man-made Lords days people assigned to God when He said its for work and labors is not going to workout so well. It didn’t in the past
Eze 22:26 Her priests have [
g]
violated My law and profaned My holy things;
they have not distinguished between the holy and unholy, nor have they made known
the difference between the unclean and the clean;
and they have hidden their eyes from My Sabbaths, so that I am profaned among them.
Revelation 1:10
I was in the Spirit on the Lord’s Day, and I heard behind me a loud voice like a trumpet
Amen, the Lords Day is the Sabbath, All other days according to God are for work and labors Exo20:9 thus saith the Lord. So if anyone was going to know when is the Lords Day wouldn’t it be the Lord Himself? He spoke what it is from His own lips no guessing needed, just faith to believe Him.
What happened after the Bible we are warned
Acts 20:29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock
2 Tim 4:3 For the time will come when they will not endure sound doctrine, but according to their own desires,
because they have itching ears, they will heap up for themselves teachers; 4 and they will turn
their ears away from the truth, and be turned aside to fables.
We need to get back to what the God of the Bible taught and kept for our example before its too late Rev18:4 Rev22:11
