Voices from the not-too-distant past need to be heard in answer to this question. The history of developments of various Greek texts needs to be understood. Here is a collection of such information I have garnered.
First, one needs to know the history of the ancient Greek manuscripts, in particular the corrupt Egyptian and Coptic influence during times of persecution in the 2nd and 3rd centuries, and the revision of manuscripts after the Council of Nicea in the 4th century. During this period of corrupt influence the Alexandrian manuscripts including Vaticanus and Siniaticus were written which now have been given vastly more weight and predominance (in the Westcott & Hort and in the Nestle-Aland UBS texts) undermining the purity of the Textus Receptus.
However, in an article by A. Hembd, he also stands against the use of the Byzantine Majority text noting that both the Hodges & Farstad and the Pierpoint & Robinson texts stem, primarily, from the 1913 text of Baron Hermann von Soden.
Hembd quotes Herman Hoskier (1864-1938, the close associate of Dean John Burgon, 1813-1888) who described, in 1914, the von Soden text as being ‘honeycombed with errors’. Hembd also reports Herman Hoskier’s work in cataloguing the huge number of discrepancies between Codex Vaticanus and Codex Sinaiticus, of which Hoskier documented no less than 3,036 in just the four gospels alone.
It is noticeable that Herman Hoskier was only seventeen years old when John Burgon wrote Revision Revised standing firmly against the substitution of a new Greek text (underlying the new Revised Version) when only an orderly adjustment of the English of the Authorised Version had actually been expected. And noticeable, also, that Hoskier was but twenty-four years old when Dean John Burgon passed away.
Now here are some quotes from Herman Hoskier dealing with various problems in the Critical Text. Bold, and capitals, are mine.
"Those who accept the Westcott and Hort text are basing their accusations of untruth
as to the Gospellists upon an Egyptian revision current 200 to 450 AD
and abandoned between 500 to 1881, merely revived in our day and
stamped as genuine." Codex B & Its Allies, Vol I, p 468
"Modern scholars love to touch on the forbidden ground of the
speculative philosophies St. Paul so often condemns in his pastoral
epistles. They touch upon it and withdraw, but the harm for the reader
is done." Codex B & Its Allies, Vol I, p 478
"The claims put forward by us are that B does not exhibit a neutral
text... That B is guilty of laches, of a tendency to "improve," and of
"sunstroke" amounting to doctrinal bias. That the maligned Textus
Receptus served in large measure AS THE BASE WHICH B TAMPERED WITH AND
CHANGED, and that the Church at large recognised all this until the
year 1881 - when Hortism (in other words Alexandrianism) was allowed
free play - and has not since retraced the path to sound tradition."
Codex B & Its Allies, Vol I, p 464
"There remains one argument to be dealt with, and that concerns the
possibility of someone saying that, after all, the variations of B are
few in number and probably less than in most MSS. That is hardly so.
If the reader wants a tenth-century example of a MS true to the Church
type let him examine Matthaei's k, a most beautiful and neat MS, one
of our very early cursives, and in this MS will be found a true
exponent of the Koine. Had Erasmus used this, no fault could have been
found, and yet BUT LITTLE DIFFERENCE IS TO BE FOUND BETWEEN K AND THE
TEXTUS RECEPTUS, WHILE B AND HIS GROUP DIFFER INFINITELY MORE AMONG
THEMSELVES AT A PERIOD MUCH MORE REMOTE." Codex B & Its Allies, Vol I,
p 456
"I present therefore an indictment against the MS B and against
Westcott and Hort, subdivided into hundreds of separate counts... If I
now throw some bombs into the inner citadel, it is because from that
Keep there continues to issue a large amount of ignorant iteration of
Hort's conclusions, without one particle of proof that his foundation
theory is correct." Codex B & Its Allies, Vol I, p i-ii
"Now in the following pages I submit a vast number of other instances
where B has a doctored text, plainly, indubitably doctored." Codex B &
Its Allies, Vol I, p vi
"The Church at large disagreed with Origen's conclusions. Westcott-Hort after nearly 1700 years merely wish to
replace us textually in the heart of an Alexandrian text, which after
AD 450 or thereabouts fell into discredit and disuse." Codex B & Its
Allies, Vol I, p 9
"We do not necessarily recover Origen's manuscripts when we are
inclined to follow Aleph and B and Origen, but very likely only Origen
himself." Codex B & Its Allies, Vol I, p 10
"Now as B does not change all these datives, it might be thought that
Antioch for some reason had made a harmonious whole and turned some
genitives into datives in the supposed revision. It is just here that
Aleph offers its important testimony, for Aleph does not use the
genitive on the first occasion, thereby showing that it was EGYPT
WHICH REVISED SOME OF ST. MATTHEW'S DATIVES, and not Antioch which
cancelled some genitives." Codex B & Its Allies, Vol I, p 35
"Finally, observe that up to the time of Westcott and Hort the lower
criticism had kept itself quite apart from so-called higher criticism.
Since the publication of Hort's text, however, and of that of the
Revisers, much of the heresy of our time has fallen back upon the
supposed results acquired by the lower criticism to bolster up their
views. By a policy of indecision in the matter of fundamental truths
of the Christian religion - truths specifically set forth by its
Founder - and by a decided policy, on the other hand, of decision in
the matter of heresy in the field of lower criticism, the beliefs of
many have been shaken not only to their foundations, but they have
been offered free scope to play the Marcion and excise whatever
appeared extra-ordinary or unintelligible to them. Many, who should
have raised their voices against the mischief wrought, have sat by in
apathy or have willfully fostered these heresies." Codex B & Its
Allies, Vol I, p 422
These various quotes deal with the matter of bias, but the last quoted paragraph speaks plainly of the matter of heresy. Needless to say, those who are against the Trinity doctrine claim to have support from the Westcott and Hort text, while accusing the Received Text of bias. It is the other way around, according to those quotes.
