A priest is blessed if he does what he has to do, called by our Lord Jesus to preach about His preaching, to instruct about His instruction, to exhort about His exhortation, to provide His goodness, His kindness, His truth. Likewise, a priest is cursed if does his own thing.
Yet, it seems like a blasphemy to teach about the Lord’s Prayer since Jesus already taught us how to pray. There is no bettering, one-upping the Lord.
But this speaks to just how weak we all are and to why our Lord called men to be priests even though Jesus is the One, the only One, the One High Priest.
Meanwhile, all the time: through, with and in Jesus, by the Holy Spirit: “Abba, Father.”
