The Law is Genesis Exodus Leviticus Numbers Deuteronomy or the Ten Commandments or all of the instruction given through Moses including the Ten Commandments and I think other things written. So yes, 613 commands, mitzvot, or commandments.
The church is not under the Law. We do not need to fulfill the Law. Jesus has done that for us. But is the Law an eternal standard or is it not? This is dangerous territory for me.
I am a Gentile, so though I have been Torah Observant, I no that I am not under the Law.
If I understand your question correctly (and I may not), it is not an external standard but a spiritual standard: anyone not brought under the auspices of the law of the Spirit of life in Christ Jesus, until and unless being placed under it, is committing sin - that law is the law transgressed and the only law upon by which salvation and judgment are assessed.
Were it to be otherwise, salvation would then be of ourselves and of our own works not of Christ's, but salvation is only through Christ and is of what He achieved, not of what we may attempt to achieve, because He alone is the Saviour.
[Rom 8:2,3 KJV]
2
For the law of the Spirit of life in Christ Jesus hath
made me free from the law of sin and death.
3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
[Jhn 16:8-9 KJV]
8 And when he is come,
he will reprove the world of sin, and of righteousness, and of judgment:
9 Of sin,
because they believe not on me;
[Tit 3:5-6 KJV]
5
Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and
renewing of the Holy Ghost;
6
Which he shed on us abundantly through Jesus Christ our Saviour;
