Part1
The art images and symbols that I see presented in religious ceremonies in churches, books, and the visual arts are: the cross and the crucifix, the good shepherd and the dove. The cross and the crucifix is one of the most acknowledged symbols presently. Christians associate with the symbol believing that Christ died on the cross to save their sins: this explains why often Christians trace the cross sign on their forehead. Secondly, the Good Shepherd’s image is often seen in many Christian’s homes and churches and always representing Jesus Christ and reminding Christians of his teachings- especially parable of the lost sheep. Lastly, the dove is a very important symbol to the Christians given that on the account of Jesus’ baptism the Holy Spirit came in form of a dove.
I think these images and symbols are repeatedly employed by the Christians over the centuries because it is what they believe in. I once saw these symbols being used by Pope John Paul the ii when he flew doves (as a symbol of peace) while praying over war between Iraqis and the Americans.
Part2
The cross and the crucifix are frequently used for traditional and cultural celebration. Particularly, before the celebration starts and when it ends, our tradition believes that every single thing is helmed by The Almighty (God the creator) so we incorporate the cross in prayers- this has been done in very generations in the past centuries.
I think this practice should never change since it links us with our forefathers- it reminds us of our roots and our cultural practices. The crucifix, as an art, is treasured and honored in our society.
