you don’t have how the hearers of the time understood what the Apostles said and wrote to them, nor how they have continued to be understood by the same Church since that time.
Your history comes to an abrupt halt at the end of the Book of Acts, and then resumes more than 1500 years later, with Martin Luther pounding his 95 theses into the door of the cathedral at Wittenberg.
The Catholic Church can only speculate as to what was going through the heads (and hearts) of the Apostles as the words of Scripture came together at their dictate. I do not believe that the Scriptures were written in some hard-to-decipher Bible Code, and if one has the context, the Word, and the intellect, the Scriptures are in most areas quite clearly defined. And with the Holy Spirit, the Word can be applied.
I do not consider myself a Protestant, *per se. *It is a tricky subject, given that non-denominationalism is a Protestant movement, yet the churches themselves are independently governed and profess no allegiance to the realm of Protestantism, but prefer the appropriate dub of “Christian,” their main reasoning drawn from the fact that the Word is their unbroken lineage. Make of that as you wish. I may attend a Baptist church, but I believe in the equality of the Church (the Body of Believers) and Christ, the necessity of water baptism with few exceptions, the antiquity of the universe, and the losibility of salvation, which makes me something of an odd-ball at First Baptist.

But I believe this not because of some persuasive argument or eloquent creed, but because the Word itself seems to attest to these things.
socializing occurs elsewhere, as does Catechesis and Bible study - the Mass is neither a classroom nor a social hall; it is a time of worship.
Yes, our church also has discipleship, Sunday school, and plenty of social events. From this alone I could have concluded that likewise the Catholic churches also in all probability have such things.
You have no support for any of this.
There is plenty of support for the Catholic understanding of the Eucharist in Scripture.
They do have plenty of arguments calling for transubstantiation, yet I remain unconvinced due to the context of the passages. Heck, the Noahide laws, which were reinforced by Paul, strictly condemn the consuming of blood. Anyway, look at my comments on the Eucharist on the thread asking to prove wrong any point of Catholic theology, and here’s a fairly unbiased Web site that does the context of these passages justice, if you’re interested:

being required to come to Mass on Sundays, many of us are there even when we’re having a bad time of it.
Protestants only have to go to Church when everything is going well
I admire that attitude. It’s a good one to have. Although most educated Protestants consider Sunday worship to be less of an obligation than something that is simply in line with the will of God, and thus they seek to fulfill their “obligation” to please him. For those that just come maybe twice a year, or just whenever they feel like it, I encourage you to be skeptical, but try not to be judgmental, for there we both would fail.
The Council of Trent reaffirmed the Declaration of Pope Damasus I which he made in something like 385 AD- it closed the canon of the Old Testament at the original 46 books that Christ and the Apostles are known to have used.
Yeshua refers to the “Scriptures” as “the Law of Moses (Torah), the Prophets (the Apocalyptic books), and the Psalms (a generic term most likely identifying the poetic narratives as a whole)” in Lk. 24:44. Neither he nor any of his disciples are ever seen quoting directly from any Apocryphal book or giving any one of them authoritative Scriptural power. And Paul said in Acts 24:14 that he believed everything in “the Law and the Prophets.” While the Apocryphal books were in circulation by that time, and while arguably the Canon was still open, officially it is often believed that the Jewish canon, which excluded the Apocrypha (with the possible exception of 2 Esdras, which was renounced by Trent anyway), was decided upon in the second century B.C. Anyway, though many of the books of the Apocrypha were accepted by the Fathers, there was tremendous disagreement as to which ones were to be admitted into the Canon and which were not. The discrepancies were a large part of the reason they were ultimately rejected. Needless to say, even the Jews, by whom and for whom those texts were crafted, did not recognize them as inspired, either. None of the Apocryphal books makes any claim of inspiration and some make historical and geographical errors. Jerome calls them simply “books of the Church,” not “books of the Canon.”
