Well done and thank you. You have pointed out the criteria Christ used to define his mother and brothers in the highest and most important sense,i.e., their spiritual family.
No name, no claims to age and legitimacy, nothing else defined Christ’s brothers, mother as these words from him.
The Jewish nation had all of these yet that nation was left to destruction because it was not doing God’s will.
What kind of sacrifices do Christians make? Heb. 13:15,16 makes clear it is our praise and the sharing of good things, especially spiritual good things, that are sacrifices that please God well.
Romans 12:1-2
1 I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. 2 Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
Hebrews 13:15-16
Through him then let us continually offer up a sacrifice of praise to God, that is, the fruit of lips that acknowledge his name. 16Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God.

The Catholic church has the whole sacrifice thing wrong.
