Even in Protestant theology, the indwelling of God the Holy Spirit and the Indwelling of Jesus Christ are two different issues.
Immediately upon having faith in Christ a number of things occur by the work of God the Holy Spirit, including these four easily memorized by the acrostic "RIBS". Regeneration, Indwelling, Baptism, and Sealing.
Nowhere in the NT is the believer commanded to be indwelt by the Holy Spirit, because the indwelling is not caused by the believer's volition, rather it is an action performed by God by His Soverignty and Grace.
The indwelling of the Holy Spirit, discernible from the OT age, where believers were endued or covered by the Holy Spirit, is unique to the Church Age. The Holy Spirit provide the temple within the believer for the indwelling of Christ (John 14:17-22)
When we have been forgiven of our sins, He is free to sanctify us. This occurs upon initial saving faith for the unbeliever and upon repentance and confession for the believer. By 1st John 1:9, we are immediately forgiven those sins and at that time we are back in fellowship with God, also known as walking with Him or being filled wih the Spirit.
Many Protestants associate the Communion as associating the Bread with the sacrifice of our Lord and Savior Christ Jesus made by allowing His body to be broken for all mankind on the Cross, and the Wine as the blood of the New Covenant sealing the covenant being made.
Many Catholics associate the Communion as the Eucharist, wherein the Bread is actually transubstantiation into the actual flesh, soul and deity of our Lord and Savior Christ Jesus, and the wine into His actual blood.
Both the Catholics and Protestants have sound counterarguments to the position of the other and many a battle and wars have been fought over the issue for centuries.
I don't know the full meaning of all the connotations implied, but I do recognize close study of Pauline theology identifying between the believer and the old sin nature, and the Johanine theologies recognizing the indwelling of the Holy Spirit and Jesus Christ in us give cause to not judge either position too rashly.
Even if the Council of Trent is correct in condemning those who take a Protestant perspective of the Eucharist, I would dare say very few Catholics are Trententine Catholics or even know the issue very well, let alone practice the full meaning of that Council's edicts.
Conversely, very few Protestants taking Communion fully grasp the doctrines of indwelling of the Holy Spirit as distinct from the indwelling of Christ who is one with the Father to fully appreciate some meanings present in the Last Supper.
Cvengr: when a Catholic in a state of grace receives Communion would you say he receives the Holy Spirit in the Host as well? And to what you wrote and adding on to my question, would we even be receiving the whole Blessed Trinity at Communion?
Never heard this before...And never seen an example of it in scripture...I've never seen in the scripture where anyone was filled with Jesus Christ (that part of the Trinity)...

I don't see where God provided a platform for sound counterarguments on both sides...Not only don't see it, can't imagine why God would even consider it...On one side, the Final Authority rests upon a priestly class of sinners...On the other, the Authority is the word of God, the scriptures...I don't see where God provided an argument for both...
