Alexander Maclaren (1826-1910), an English non-conformist minister, said this in his commentary on Christ’s triumphal entry from Luke 19:28-40. I appreciate the well-stated and pointed challenge to us; worth pondering.
High-wrought emotion is a poor substitute for steady conviction. But cool, unemotional recognition of Christ as King is as unnatural. If our hearts do not glow with loyal love, nor leap up to welcome Him; if the contemplation of His work and its issues on earth and in heaven does not make our dumb tongues sing—we have need to ask ourselves if we believe at all that He is the King and Saviour of all and of us. There were cool observers there, and they make the foil to the glad enthusiasm. Note that these Pharisees, mingling in the crowd, have no title for Jesus but ‘Teacher.’ He is no king to them. To those who regard Jesus but as a human teacher, the acclamations of those to whom He is King and Lord always sound exaggerated.
People with no depth of religious life hate religious emotion, and are always seeking to repress it. A very tepid worship is warm enough for them. Formalists detest genuine feeling. Propriety is their ideal. No doubt, too, these croakers feared that this tumult might come to formidable size, and bring down Pilate’s heavy hand on them (Alexander Maclaren, Expositions of Holy Scripture: Luke, 323).
