As the question asks, which verses in the Bible show that Jesus Christ consecrated the disciples as apostles during his lifetime. Also are there any verses(with words of Jesus in his lifetime) which talk in general about their infallibility. Please support your answer with authentic references.
And the definition of authentic according to me is ...
Authentic - If a source is authentic, then it is proved that it is not fake or fabricated over time by the people passing it, but in fact it was in its true form real and original.
Update: As suggested below I would like to ask the same question this way, if this is what the community prefers...
What biblical evidence, does the Church use to support the claim, of the papal infallibility in the Catholic Church, and under what grounds does it claim infallibility and it’s ability to teach without error?
