Do Protestants worship Jesus apart from the Eucharist?
Yes, in the same way that Muslims worship the God of Abraham without Christ and the HS.
Um…because they deny the true God… the Trinitarian God…they deny Christ…they deny the Holy Spirit…and St John tells us that “whosoever denieth the Son, the same hath not the Father.”
Islam is based on what the sons of Ishmael recieved as spiritual descendants of Abraham. As a result, what has been revealed to them is limited, and predates all of these revelations of God by Himself.
God told Abraham that the faith would be passed through His son Isaac. Abraham made a plea for his other son, Ishmael. Because Abraham loved God, God blessed his other son also.
Gen 17:18-27
And Abraham said to God, “O that Ishmael might live in your sight!”
19 God said, “No, but your wife Sarah shall bear you a son, and you shall name him Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. 20
As for Ishmael, I have heard you; I will bless him and make him fruitful and exceedingly numerous; he shall be the father of twelve princes, and I will make him a great nation. 21 But my covenant I will establish with Isaac, whom Sarah shall bear to you at this season next year.” 22 And when he had finished talking with him, God went up from Abraham.
23 Then Abraham took his son Ishmael and all the slaves born in his house or bought with his money, every male among the men of Abraham’s house, and he circumcised the flesh of their foreskins that very day, as God had said to him. 24 Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin. 25
And his son Ishmael was thirteen years old when he was circumcised in the flesh of his foreskin. 26 That very day Abraham and his son Ishmael were circumcised;
Ishmael was also circumcised, and given a blessing by the GoKd of Abraham. It is upon this basis that the CC acknowledges that the descendants of Ishmael worship the God of Abraham.
This blessing came millenia before the Koran, and the invention of modern Islam.
