"They [heretics] gather their views from other sources than the Scriptures...We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us, which they did at one time proclaim in public, and, at a later period, by the will of God, handed down to us in the Scriptures, to be the ground and pillar of our faith....
It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the apostles manifested throughout the whole world; and we are in a position to reckon up those who were by the apostles instituted bishops in the Churches, and to demonstrate the succession of these men to our own times; those who neither taught nor knew of anything like what these heretics rave about. For if the apostles had known hidden mysteries, which they were in the habit of imparting to 'the perfect' apart and privily from the rest, they would have delivered them especially to those to whom they were also committing the Churches themselves. For they were desirous that these men should be very perfect and blameless in all things, whom also they were leaving behind as their successors, delivering up their own place of government to these men; which men, if they discharged their functions honestly, would be a great boon to the Church, but if they should fall away, the direst calamity....proofs of the things which are contained in the Scriptures cannot be shown except from the Scriptures themselves." - Irenaeus (Against Heresies, 1:8:1, 3:1:1, 3:3:1, 3:12:9)Selective quoting sure helps to make the point you want to make. However, taking things out of context tends to distort the truth. So it is with all of your quotes.
Don’t you know that the laying on of hands after baptism and then the invocation of the Holy Sirit is a custom of the Churches? Do you demand Scripture proof? You may find it in the Acts of the Apostles. And even if it did not rest on the authority of Scripture the consensus of the whole world in this respect would have the force of a command. For many other observances of the Churches, which are do to tradition, have acquired the authority of the written law Jerome (The Dialogue Against the Luciferians 8 [A.D. 382]).They claim Sola Scriptura.Of the beliefs and practices whether generally accepted or publicly enjoined which are preserved in the Church some we possess derived from written teaching; others we have received delivered to us "in mystery" by the tradition of the Apostles; and both of these in relation to true religion have the same force. And these no one will contradict; - no one, at all events, who is even moderately versed in the institutions of the Church. For were we to attempt to reject such customs as have no written authority, on the ground that the importance they possess is small, we should unintentionally injure the Gospel in these matters… Basil (On the Holy Spirit 27 [A.D. 375]).

Nothing in that quote changes what he said in the quote I posted.
If Jerome and Basil changed their statements why would you even consider them credible?
