Technology is liberating only if we allow ourselves to be touched by God's love, Pope Benedict said on Palm Sunday.
VATICAN CITY — Celebrating Palm Sunday Mass at the Vatican April 17, Pope Benedict warned that technological progress must not lead people to think they can "become God."
The German pontiff, who celebrated his 84th birthday the day before, joined a Palm Sunday procession that went through St. Peter's Square before Mass.
In his homily, Pope Benedict said the Palm Sunday procession must be understood as more than a "quaint custom." It represents the spiritual ascent that all Christians are called to make, a journey "along the high road that leads to the living God," he said.
Such an ascent is impossible without God's help, he said, although men and women have long attempted to "attain the heights of God by their own powers."
All the inventions of the human spirit are ultimately an effort to become independent and completely free - but without God, this effort is doomed to failure, he said.
"Mankind has managed to accomplish so many things: We can fly. We can see, hear and speak to one another from the farthest ends of the earth," he said.
"And yet the force of gravity which draws us down is powerful. With the increase of our abilities there has been an increase not only of good. Our possibilities for evil have increased and appear like menacing storms above history."
He described people as caught between two "gravitational fields": the force of gravity that pulls people down toward selfishness, falsehood and evil, and the force of God's love that pulls people up.
The spiritual ascent to which Christians are called has some concrete elements, including purity, honesty and faith in God, he said.
"The great achievements of technology are liberating and contribute to the progress of mankind only if they are joined to these attitudes — if our hands become clean and our hearts pure, if we seek truth, if we seek God and let ourselves be touched and challenged by his love."
In the end, he said, a spiritual ascent is effective only if people humbly acknowledge that they need God and "abandon the pride of wanting to become God."
