During our mass, we recieve Jesus' real flesh and blood, presented under the appearances of bread and wine. Joh 6:53-55. This was also prophecized in Malachi 1-11, "From the rising of the sun, even to its setting. . . they bring sacrifice to my name and a pure offerring. Earthly bread nourishes our bodies, Jesus, nourishes our souls.
We honor the saints who served our Savior. There is nothing wrong with that. We have a rich tradition and God encouraged that, why wouldn't you? "Stand firm and hold fast to traditions that you were taught, either by oral statement or by a letter of ours." 2 Thessalonians 2:15
As long as you know that only through Jesus and receiving Him into your heart is the way to salvation, that’s what counts. None of the other stuff really does.
