You are ignoring the the relevant phrase “is profitable..” TRUTH in Scripture... and depending on traditions of men. Isaiah was right about you guys, too!
Mark 7:6 He replied, “Isaiah was right when he prophesied about you hypocrites; as it is written:
“‘These people honor me with their lips,
but their hearts are far from me.
7 They worship me in vain;
their teachings are merely human rules.’
8 You have let go of the commands of God and are holding on to human traditions.”
9 And he continued, “You have a fine way of setting aside the commands of God in order to observe your own traditions! 10 For Moses said, ‘Honor your father and mother,’ and, ‘Anyone who curses their father or mother is to be put to death.’ 11 But you say that if anyone declares that what might have been used to help their father or mother is Corban (that is, devoted to God)— 12 then you no longer let them do anything for their father or mother. 13 Thus you nullify the word of God by your tradition that you have handed down. And you do many things like that.” ...

Colossians 2: ... 8 See to it that no one takes you captive through hollow and deceptive philosophy, which depends on human tradition and the elemental spiritual forces[a] of this world rather than on Christ. ... 2 Thessalonians 2: ... 8 And then the lawless one will be revealed, whom the Lord Jesus will overthrow with the breath of his mouth and destroy by the splendor of his coming. 9 The coming of the lawless one will be in accordance with how Satan works.He will use all sorts of displays of power through signs and wonders that serve the lie, 10 and all the ways that wickedness deceives those who are perishing. They perish because they refused to love the truth and so be saved. 11 For this reason God sends them a powerful delusion so that they will believe the lie 12 and so that all will be condemned who have not believed the truth but have delighted in wickedness.
13 But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruits to be saved through the sanctifying work of the Spirit and through belief in the truth. 14 He called you to this through our gospel, that you might share in the glory of our Lord Jesus Christ.
