The Eucharist is the Body, Blood, Soul and Divinity of Jesus Christ, our Lord. Thus, your question, to us, is a false dichotomy. The Most Blessed Sacrament is Jesus with us in His Sacramental Presence. That Presence is at close as we get to Heaven in this life.
I don't see how this addresses "source of faith". Presence doesn't mean a transfer of faith (necessarily).
And thus, the Sacrifice of the Mass, which is the offering of the Body, Blood, Soul and Divinity of Christ to God the Father, with His entire Church joined to Him (which is also His Body), is on earth the supreme act of worship for Catholics.
If it is the supreme act of worship then that mandates that you already had faith before you participated in it. How can it then be the source? :)
In the Mass, we become present at Calvary and are joined to the Sacrifice Jesus made on the Cross.
What does this mean? I can think of some possibilities that sound pretty bad, so maybe it would be better if I just let you answer first. :)
However, regarding prayer alone, I'll say this: all prayer to the saints is conditioned on the premise that it's all God. Personally, when I pray to saints in my own words, I ask them to pray for me. Even prayers to Mary, which include the highest praise that may be offered to a human creature, generally include or end with petitions to her to pray for us. But when I pray to God in petition, I never ask God in prayer to pray for me. God, I petition for the thing itself, whatever it is.
OK, I'd say that addresses well many of the strongest criticisms of Protestants concerning the subject. That matches the analogy often given of asking a friend for prayer. However, as many of us on the other side have done, it is easy to find published prayers to Mary that read like this - Petition to Mary by Saint Alphonsus Liguori :
This is by no means an isolated example, so I'm sure you can imagine what is going through our minds when we read prayers (by a Saint no less) like this. :)
I will ask you again, please, do not ping me to your every reply to this—or any—thread.
I SO get that!
I love Alphonse Liguori. But I really recognize that he is an acquired taste.
Nancy and I still sort of randomly insert (ahem, by your intercession) when we read stuff like that.
Catholic Piety and culture are lush, extravagant, stuff that I as, by culture, an Episcopalian - God’s Frozen People — find a little icky. I mean, you start talking like that, you might end up using the wrong fork!
Whew. The blowback from that kind of error could be fearsome.
Where does Scripture say are we to serve anyone in heaven but the Triune God alone?
