Yes, and to add some thoughts, FWIW. As to the Body and Blood, this brings to mind the reason for the “Do this in memory of Me" verse. Because the regular doing of the sacrament is for the purpose of keeping us reminded of our continuous need for Him and the nourishment implied simply in our freely partaking of Him. It isn't just some memorial service, IOW, but the fulfillment of a vital necessity. We need to know that we require this divine contact regularly, lest we forget, and begin slipping away into mundanity or worse.
And the sacraments have that as their purpose. They "cement" basic Christian theology into acts that can easily be understood and carried out. We must be baptized (the sacrament of faith) in order to enter God's fold. We can argue all day long about the thief on the cross and God's ability to forgo the necessity of any particular command being physically fulfilled and Scripture can sorta kinda be argued either way on this but we know what Jesus both modeled and commanded and we know what the early churches everywhere believed and practiced so there should be no real question as to what God gives as the normative way of coming to Him. In any case, come to Him we must and that sacrament makes this necessity clear, while serving as a definitive public profession of our faith as the way to do it.
The Eucharist is clearly enough described in Scripture as being central to the regular gathering of the church along with the reading of the sacred writings. And it was taken so seriously that one should not even partake without examining their consciences first (1 Cor 11:28-29). This demonstrates 1) that the intimate, ongoing communion with our Lord is essential to our spiritual health, to our life, and 2) that this vital communion can be threatened by our returning to the flesh, by our engaging in sin that is radically opposed to love of God and neighbor.
But, if we have a change of heart and confess our sins, He’ll purify us from all unrighteousness (1 John 1:9). So, we’re provided a definite “place to go” for this need, so that complacency in observing it isn’t easily allowed to prevail. The sacrament of Confession/Reconciliation is for that very purpose, of reestablishing communion with God if we’ve seriously strayed away from Him. I believe this sacrament isn’t recognized by most Lutherans, but I’ve come to appreciate it and the reason behind it.
Anyway, by these simple sacraments even the simplest of folk can both know the most basic part they must play while having the practical means to play it, with all of these pointing to the need for and the reception of God’s grace. Any and all of these can be done cavalierly, mechanically, without sincere faith, but then they’ll be of no value either way.
