Why did the Lord Christ make known His resurrection only to His own followers?

The Lord Christ was crucified openly in public, in front of the Jewish leaders and people as well as in front of the Roman military commanders and soldiers so as to proclaim His love and His sacrifice to all, Jews and Gentiles. But His resurrection was revealed only to those

who were ready to believe in Him and prepared to live the resurrected life and to preach His resurrection as a sign of the Father’s acceptance of His sacrifice on behalf of humanity. The apostle Paul says, “But now Christ is risen from the dead, and has become the first fruits of those who have fallen asleep” (1 Cor. 15:20).

St. Augustine says, “Let us see the Son indeed, and not the Father, rising again, but both the Father and the Son working the resurrection of the Son. The resurrection of the Son is the work of the Father; for it is written, ‘Therefore He exalted Him, and gave Him a name which is above every name’ (Phil. 2:9). The Father therefore raised the Son to life again, in exalting, and awakening Him from the dead. And did the Son also raise Himself? Assuredly He did. For He said of the temple, as the figure of His own body, ‘Destroy this temple, and in three days I will raise it again’ (John 2:19). Lastly, as the laying down of life has reference to the Passion, so the taking it again has reference to the resurrection … For that the Father restored it is plain. For so says the Psalm, ‘Raise Me up, and I will requite them’ (Ps. 41:10). But why do you wait for a proof from me that the Son also restored life to Himself? Let Him speak Himself; ‘I have power to lay down My life.’ I have not yet said what I promised. I have said, ‘to lay it down’; and you are crying out already, for you are flying past me. For wellinstructed as you are in the school of your heavenly teacher, as attentively listening to, and in pious affection rehearsing, what is read, you are not ignorant of what comes next. ‘I have power,’ says He, ‘to lay down my life, and I have power to take it again. No man takes it from Me, but I lay it down of Myself, and take it again.’”⁶⁹³
