No. The nature of the elements was never described as being an issue, nor in Pauline theology is the nature of such ever expounded upon, which it would be if understanding it was important as a means of grace for the body, let alone if having Cath importance, and in which even individual "communion" (an oxymoron) is critical if not able to make it to "Mass."
Instead, it is the hearing of the word of God that is said to "nourish" believers (1Tim. 4:6) and build them up," (Acts 20:32) with Peter also teaching that the sincere milk of the word is what one grows by, (1Pt. 2:2) and which Paul fed the Corinthians with, and lamenting that believers were not yet ready for "meat," (1Co. 3:2). and with the writer of Hebrews exhorting receiving the "meat" of the word. (Heb. 5:13-6:2) And which Scripture being the wholly inspired, assured transcendent substantive body of Truth, which instrumentally is used to make one "perfect, throughly furnished unto all good works." (2 Timothy 3:16,17) Glory to God, and what the oral preaching of the word is subject to testing by. (Acts 17:11)
And with the preaching of it (and prayer) being the primary ordained function of NT pastors, (Acts 6:4; 2Tim. 4:2) not dispensing anything which was physically eaten, which nowhere in Scripture provided spiritual life.
