As can be seen from the gospel of John, the doctrine of the Real Presence, amongst other things, is a test of faith.
I accept said doctrine only because the Catholic Church teaches it - it must be true because the CC is the “fullness” of Christ (Eph1:22-23).
For me, none of this makes any sense if this isn’t true.
I was baptized as a baby, but complicated family issues ended my regular church attendance to seldom if at all. As I got older I found myself interested in God. I began watching TV shows & things they said made sense. But of course there were more questions. I began reading the Bible & some questions were answered, but more questions came as well.
I went back to the Church my mom brought me to, Catholic. More answers, more questions.
I took a comparative religion class… not a lot of answers came out of that. Questions, yes. But no answers.
Then one day as I was praying I came across John 6 & it hit me like a ton of bricks. I found a book I had bought years earlier about Eucharistic miracles & it made sense… in a way it didn’t before. I didn’t necessarily believe that these things happened but I began to “see” the reality the Church professed as truth.
The prayers of the Mass made sense, the priesthood made sense, the Kingdom of God made sense. The sacrifice of the Mass, the priesthood of Christ, Exodus, the Love of God… all made sense & makes sense.
All things reconciled in the Eucharist, in Christ.
So, I don’t believe the real presence because the Church teaches it. I believe the Church because she teaches the real presence.
