Strange that you would commend the Douay-Rheims Bible when its own preface states,
Which translation we do not for all that publish, upon erroneous opinion of necessity, that the Holy Scriptures should always be in our mother tongue, or that they ought, or were ordained by God, to be read impartially by all...to have them turned into vulgar tongues, than to be kept and studied only in the Ecclesiastical learned languages...
In our own country...[was] no vulgar translation commonly used or employed by the multitude, yet they were extant in English even before the troubles that Wycliffe and his followers raised in our Church.. . - Preface to the Douai-Rheims New Testament Translation of 1582; (http://www.bombaxo.com/douai-nt.html)
Certainly, read Sacred Scripture. All of the Church Fathers did--and they understood it much better than we do today. Heck, they lived in the same civilization that produced it!
And based on the same logic the same could be said of the Scribes and Pharisees, who actually did sit in the seat of Moses. Yet the common people had better discernment, and honestly, in holding John the baptizer to be "a prophet indeed" and gladly hearing an Itinerant Preacher and preachers who established their Truth claims upon Scriptural substantiation in word and in power. (Mt. 22:23-45; Lk. 24:27,44; Jn. 5:36,39; Acts 2:14-35; 4:33; 5:12; 15:6-21;17:2,11; 18:28; 28:23; Rm. 15:19; 2Cor. 12:12, etc.)
And thus the church actually began in dissent from those who sat in the seat of Moses over Israel, (Mt. 23:2) who were the historical instruments and stewards of Scripture, "because that unto them were committed the oracles of God," (Rm. 3:2) to whom pertaineth" the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises" (Rm. 9:4) of Divine guidance, presence and perpetuation as they believed, (Gn. 12:2,3; 17:4,7,8; Ex. 19:5; Lv. 10:11; Dt. 4:31; 17:8-13; Ps, 11:4,9; Is. 41:10, Ps. 89:33,34; Jer. 7:23)
The fundamental error many lot souls make is that of making the uninspired writings of post-apostolic men (or more accurately, what their self-proclaimed infallible church selectively chooses from them) determinitive of what the NT church believed, versus the only wholly inspired substantive authoritative record of what the NT church believed (including how they understood the OT and gospels) is Scripture, especially Acts thru Revelation.
In which distinctive Catholic teachings are not manifest .
Catholic:
Then came the officers to the chief priests and Pharisees; and they said unto them, Why have ye not brought him? The officers answered, Never man spake like this man. Then answered them the Pharisees, Are ye also deceived? Have any of the rulers or of the Pharisees believed on him? But this people who knoweth not the law are cursed. (John 7:45-49)
Truthful:
And Jesus answered and said, while he taught in the temple, How say the scribes that Christ is the Son of David? For David himself said by the Holy Ghost, The Lord said to my Lord, Sit thou on my right hand, till I make thine enemies thy footstool. David therefore himself calleth him Lord; and whence is he then his son? And the common people heard him gladly. (Mark 12:35-37)
