Were Irenaeus and Hyppolitus trustworthy?

Question

I know these two leaders were from the post-apostolic age.

Answer 1

Yes, a better question is why do you ask?

Answer 2

Sure. Irenaeus, the great Bishop of of Lyons wrote his Against Heresies c. 175-185 A.D.

His work is invaluable to modern scholarship in the attempt to recover the content of Gnostic teachings in the second century. Irenaeus also provides the first explicit witness to a four-fold gospel canon.

I still use some of his stuff in composing sermons. He was a genius.

Answer 3

Yes,
As far as Irenaeus is concerned,
He repeatedly reaffirms belief in “one God, the Father Almighty, who made the heaven, and the earth, and the seas, and all that is in them, and in one Christ Jesus, the son of God, who was made flesh for our salvation.” These facts the Gnostics denied, along with currrent triune beliefs that there is a godhead made up of three distinct persons.

As far Hippolytus is concerned,
It wasn't until the fourth century A.D. did the teaching that the holy spirit was a person and part of the “Godhead” become official church dogma. Early church “fathers” did not so teach; Justin Martyr of the second century A.D. taught that the holy spirit was an ‘influence or mode of operation of the Deity’; Hippolytus likewise ascribed no personality to the holy spirit. The Scriptures themselves unite to show that God’s holy spirit is not a person but is God’s active force by which he accomplishes his purpose and executes his will.

They, along with Polycarp and others, was against the developing belief, that is now called Catholicism

Answer 4

Absolutely. Their teaching was true to the Apostes.

Answer 5

They were heretic hunters and enormous ignoramuses, and liars.
