We experience nothing that the disciples and later the apostles did not experience.
In Mark 9:38-41 disciples run up to Jesus, like dogs wagging their tails, thinking that they have done a good deed by "sending away" men doing good works in Jesus' name "because they don't follow us".
Read Jesus' correction, and take it to heart.
The audacity of confirming the validity of this man doing ministry in the name of the Lord when not part of the company what RCs consider to be their church. For the traditional (not this pope's) Catholic position is that no one has the commission and the right to preach the gospel if not sent by her, and that "he that hears/reject you, hears/rejects Me," does not apply to Prots.
