It does not say in scripture that monday or any other days are HOLY....why are you contradicting GOD ?
Your own opinion/understanding is at work which we are told not to indulge in...why ? because it is from another spirit. Learn to speak the words of GOD !
It does. It says that all days are equal. Just read it.
"One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind."
R 14:5
