Scripture does not give us the complete story of his reaction, but when Joseph discovered that Mary was expecting, he was advised to quietly dissolve the relationship. Apparently Joseph sought what he thought was wise counsel because he truly loved Mary and wanted to do the right thing and not cause her any harm, emotionally, physically or spiritually. God sent an angel (most likely Gabriel) to inform Joseph of the situation and that he should not be afraid to take Mary as his bride. Joseph and Mary showed great faith and trust in God and each other. One can only wonder how Joseph dealt with their situation on a daily basis, because people are going to talk. After all, it wasn’t his child.
