We sing "All are welcome" but do we believe it? Many of us think about welcoming the unwanted or non-Catholic or poor or fallen-away. What about ourselves? If we are really honest, do we sincerely believe that we are welcome here? 
We all know our sins, our faults and the guilt that clouds our minds. However, many of us think we aren't such bad people, really. I mean: "Rebelled, revolted, hard of face, obstinate" - do these words from our first reading sound like you?
What about our second reading: "a thorn in my flesh," something that does not kill or keep us separated from God's love and grace, but that still bothers us, something we ask to have removed as St. Paul did. but it is still there, in me, in you, keeping us humble? What about that thing? What guilt surrounds it? Does that part of you feel welcome? What do you do with it?
The GIRM describes the Eucharistic Prayer and Sacrifice as the "center and high point" of what we do at Mass. Part of that prayer is the Lord's Prayer, where we say, "Thy will be done." We say that we aren't so rebellious, hard-faced, obstinate, but how often do we pray "thy will be done so long as it is not x, y, and z and only if it includes a and b"?  Stubborn? Maybe so...
So, we have this desire to feel welcome and to respond to God's grace by simply being here on Sunday. Yet, even at the highest point of the Mass, we acknowledge our own lack of ability to respond, our own selfishness. Just talking about having this tension makes us uncomfortable.
So what do we do with it?
Maybe it is not such a bad thing - believing enough to just touch the hem of Jesus' garment, to have faith the size of a mustard seed. The people in the Gospel today, they had little faith, so little that "He was amazed" at it. We, however, can take some solace in the faith we do have. And, when we bring that little bit - those two coins, that desperate touch of the hem - to the altar as Christ is made present to and for us, maybe this unsettling tension will transform us, give us faith, bring us to Jesus, and really make us feel totally welcome.
Jesus comes to the sick, the unwanted. He comes to us all. And, those dark sides of ourselves that we hide or run from? Those are the things that we should be most eager to be rid of - to, like St. Paul, ask to be free from not once but three times.
What is on our heart? What divisions between "thy will" and "my will or my fear" is the source of the tension in you? What stirs within that the Holy Spirit is wanting to take to Jesus Christ? Today, in this Eucharist, silently and prayerfully set them on the altar with the bread and wine to be taken by Christ and transformed as you are transformed in the hope of Jesus' redeeming gift.

• GIRM 78. "Now the center and high point of the entire celebration begins, namely, the Eucharistic Prayer itself, that is, the prayer of thanksgiving and sanctification. The Priest calls upon the people to lift up their hearts towards the Lord in prayer and thanksgiving; he associates the people with himself in the Prayer that he addresses in the name of the entire community to God the Father through Jesus Christ in the Holy Spirit. Furthermore, the meaning of this Prayer is that the whole congregation of the faithful joins with Christ in confessing the great deeds of God and in the offering of Sacrifice. The Eucharistic Prayer requires that everybody listens to it with reverence and in silence."
