The key word there is "seem." No serious Catholic thinks images of the saints or Jesus are the actual "real deal." No saint has power of their own, other than that of their prayers. All is done in accordance with the Will of God.
The real issue, and the truth, is that post-Luther Christians worship God only by word and song, when higher worship, the Divine Liturgy (or Mass in the Western Christian tradition), is due the Holy and Undivided Trinity.

These folks could learn a lot from Rosalind Moss who is often on EWTN. She is an excellent speaker who is able to marry her Judaism with her Hebrew Catholic faith.

No serious Hindu thinks that images of Shiva, Kali, or Vishnu are the actual "real deal" either. In fact, in modern Hindu theology, they're all just incarnations of the Brahman, or God, when you get right down to it.
Yet we still call bowing down in front of a statue of Vishnu idolatry . . .
