The following items are highly debated around Christian circles:
Skirts for women
Headcoverings for women
And bazillions of other things
I'll spell out my take on it here. *ahem*
Nothing but the blood of Messiah/Christ will get you into Heaven, so if you understand why He was crucified for you and accept His salvation, you WILL hang out with me in Heaven one day. The other things are unnecessary for salvation from the fires of hell, but the lifestyle parts are good ideas to incorporate into your life. Why? Because He (YHVH/God) likes it. He wouldn't have said to do something if He didn't like it. But they will not save you.
Baptism exists as a public symbol of acceptance of salvation. Just like a wedding is a public symbol of marriage. A marriage happens when a man and woman commit to each other for the rest of their mortal lives. Weddings are irrelevant to marriage. Salvation is between a man/woman/child and YHVH/God. Baptism is irrelevant to salvation. They are nice symbols, though.
The person whose life could only be described as an abomination that accepts the Lord as they breathe their last breath alone in that hospital room is just as saved as someone who accepted Him at the age of 10, was baptized, and lived a righteous life.
So there ya go. Good ideas, but they are not a path to salvation. More like a path after salvation.
