Transubstantiation: Why the lack of Controversy in the Early Church?

For those that believe in transubstantiation, that the bread and wine of the Eucharist literally become the flesh and blood of Christ, why were there no schisms concerning this within the Early Church IF this is what they believed and taught? The Noahide Covenant and the Mosaic Law not only both expressly forbid the consumption of blood - with the penalty of being cut off from Israel - but it is one of the few commands deemed essential for Gentile converts to follow as well, despite not being under the Mosaic Law. It is thus not simply a matter of ceremonial cleanliness at stake; but an ex-communicable offense. The early church itself was composed of Jewish converts who carried with them their previous beliefs. This led to controversies like demanding that Gentiles get circumcised and to those who claimed within the church that there was no resurrection (like the Sadducees) as well as to controversies over what food they were permitted to eat amongst Gentiles. Such concerns are clearly reflective of Jewish religious life back when. Now, if the disciples and apostles had gone around preaching that the Eucharist literally was flesh and BLOOD - do you not think that this would have caused not a little controversy amongst the Jewish Christians? Would not Paul have to defend why he was not cut off from Israel - let alone how Gentiles are grafted onto Israel - if they routinely committed an excommunicatable offense? And even if fellow Christians could be convinced of the matter - it surely would have been a point of objection from those Jewish authorities that sought to persecute the Church; like Paul prior to his conversion. Yet the biblical testimony is absolutely silent on such a controversy. Nor, again, do the Church Fathers record such a controversy; even in their lengthy volumes recording actual or fictional conversations with Jews. The closest we get are apologies against those who assert that Christians were cannibals - a valid claim IF the Eucharist is literal flesh and blood.
