[16] And the eleven disciples went into Galilee, unto the mountain where Jesus had appointed them. [17] And seeing him they adored: but some doubted. [18] And Jesus coming, spoke to them, saying: All power is given to me in heaven and in earth.

[20] Teaching them to observe all things whatsoever I have commanded you: and behold I am with you all days, even to the consummation of the world.
Matthew; Chapter 28
[18] All power: See here the warrant and commission of the apostles and their successors, the bishops and pastors of Christ’s church.

How then could the Catholic Church ever go astray; having always with her pastors, as is here promised, Christ himself, who is the way, the truth, and the life. St. John 14.

14 And if any one will not receive you or listen to your words, shake off the dust from your feet as you leave that house or town...
Coming Persecutions
16 “Behold, I send you out as sheep in the midst of wolves; so be wise as serpents and innocent as doves... 19 When they deliver you up, do not be anxious how you are to speak or what you are to say; for what you are to say will be given to you in that hour;
20 for it is not you who speak, but the Spirit of your Father speaking through you.
23 When they persecute you in one town, flee to the next...
