The Jews didn't believe in preaching the gospel to all nations, either. But Jesus sure does.
Worshiping in the temple by early Apostles or other disciples didn’t end with the rending of the veil at Christ’s Crucifixion. The NT has plenty of references to such, well after Christ was gone and the law fulfilled.
The rending of the veil in the holy of holies at the death of Christ was a symbolic opening up of the temple to those outside of levitic lineage, and the fulfillment of the Law of Moses.
