At least not in the technical sense of the Roman Catholic Church, because he was never officially canonized. According to the encyclopedia Patrick “passes as a saint merely by popular approval”.
Did you know that Patrick is claimed by Catholics and Protestants? All we can say, whatever his affiliation, he was an evangelical preacher and he never appealed to the authority of any creed, ecclesiastical leader or council,
.“The Greek word for holiness is ‘hagiasmos’ which literally means ‘to be set apart’. In the Bible it is the same word that is translated ‘sanctification’. ‘Hagios’ is the same root word we translate ‘saints’ but could also be translated ‘holy ones’. Believers are al- ways referred to as ‘saints’ in the Bible. Only once are they called Christians in Acts 11:26…And the disciples were called Christians first in Antioch. Only twice are they referred to as believers in Acts 5:14 /1Timothy 4:12. Everywhere else they are called saints or ‘holy ones’.” excerpt Page 168 DEVELOPING A SECRET HISTORY WITH GOD
So you see according to Biblical standards Patrick truly was a saint and set apart for the use of God.
1 Corinthians 1:2 Unto the church of God which is at Corinth, to them that are sanctified in Christ Jesus, called to be saints, with all that in every place call upon the name of Jesus Christ our Lord.
