Well, God in Scripture, the Revealed Word of God, calls some people perfect...these are from a protestant website , but you can look up the Scripture in the Catholic Bible. I apologize for not having enough time tonight on the Net to look up the Douay Versions.
"Gen 6:9 --- Noah was a just man and perfect in his generations, and Noah walked with God. 22 Thus did Noah; according to all that God commanded him, so did he."
"Job 1:8 And the LORD said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?"
"Gen 17:1 And when Abram was ninety years old and nine, the LORD appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect".
"Phil 3:15 Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you."
"1 Cor 2:6 Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world,---."
"Col 1:28 Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus: 29 Whereunto I also labour, striving according to his working, which worketh in me mightily."
"Heb 5:8 Though he were a Son, yet learned he obedience by the things which he suffered; 9 And being made perfect, he became the author of eternal salvation unto all them that obey him;"
