I just watched a really good video from Matt Fradd from the Pints with Aquinas YouTube channel. In it he talks about the beliefs of early Christians and how they saw the Eucharist or Communion.
In the video he quotes the early church fathers and other leaders down through the ages who all agreed that the elements truly become the body and blood of Christ once prayed over.
If you are interested in what the church has believed down through the ages I would encourage you to watch the 14 minute video. It is well researched and presented. You can find it here on his YouTube channel.
