Maybe, but as the 10 are holy, spiritual, and good as Paul tells us in Romans 7...
Well, anything God has said or done in the past, but which does not apply to us today, is still viewed as "holy, spiritual, and good." That would mean that animal sacrifices under an Aaronic/Levitical priesthood is still viewed as "good" today. It's just that it was "good in the time of its own particular covenant." Temple worship would still be viewed as "good in its time," even though it is no longer applicable today.
We need not find a "NT equivalent" to see it as something we are obeying today. The principles they represent are what we obey today. We don't follow a NT equivalent of a physical temple, as in a church building. We follow Christ as a completely different kind of temple, for example.
Paul is talking about maintaining the same mindset as that Israel had maintained under the Old Covenant, that he should be interested in pursuing whatever is still good for us today, namely the eternal Law of God, as opposed to the temporal Law of Moses.
If it had been good for Israel to obey the Sabbath Law under the Old Covenant, because prior to final redemption God saw fit to cause Israel to acknowledge a need to rest from theior works, then it is equally good today to acknowledge that the need for our works to be "limited" is no longer required due to the work of Christ which has brought us into God's eternal rest.
and as Jesus isn't against saying in Matt 19 that the 10 are necessary in order to enter life, and as the 10 are simply reflections of the two greatest, based on love as they are, and as the early churches always upheld them as necessary even while acknowledging that true obedience of them is only authentic and possible by the Spirit...
Jesus was speaking in Matt 19 while Israel was still under the Law of Moses. Just as today things are to be done by the heart and by the Spirit, so Israel at that time was to obey the commandments of the Law by the heart and by the Spirit.
The difference today, is that we don't see the Sabbath, the Temple worship, the sacrifices, and the Priesthood as the "good" that it was for Israel, pre-Redemption. They were all "good," as you say, at that time. But they are no longer "good" for us today, if it causes us to reject Christ's work in rendering those things unnecessary for our redemption.
, and, finally, since the early churches saw Sunday, the Lord's Day, as fulfilling the Sabbath obligation for rest and worship, still recognizing the need to set aside a day for acknowledgment and devotion to God, I kind of think It's good to understand that they are speaking of a true righteousness, while one that the law and the prophets testify to without being able to accomplish, that we still must live up to to but in a new way, and with a new day centered on the resurrection, now.
I think the replacement of Sabbath observance with Sunday worship was a failure to recognize that the moral principles of the 10 Commandments could be transferred into the New Covenant without transferring the Sabbath requirement as well. It may also have simply been a wish to transfer the Jewish tradition of a weekly rest day with something Christian. This Christians did with pagan holidays, as well, converting them into Christian traditions.
