The Sabbath is a day of the week like any other day Rom. 14.5 is clear on. It does not require it say the word Sabbath,

“One man esteemeth one day above another: another esteemeth every day alike. Let each man be fully assured in his own mind. He that regardeth the day, regardeth it unto the Lord; and he that eateth, eateth unto the Lord, for he giveth God thanks; and he that eateth not, unto the Lord he eateth not, and giveth God thanks” (Rom. 14.5-6).

God does not want us to waste too much time on false Christians. Hence, your infractions are building when the burden of the proof is on you as you repeat yourself.
