Simply proclaim the Lord Christ holy in your hearts, and always have your answer ready for people who ask you the reason for the hope that you have. But give it with courtesy and respect and with a clear conscience. Saint Peter (1 Peter 3: 15-16)
I remind you to stir into a flame the gift of God that you have received … For God did not give us a spirit of timidity, but rather of power and love and self-control. So do not be ashamed of your testimony to our Lord … but bear your share of hardship for the Gospel with the strength that comes from God.
Saint Paul in his second letter to Saint Timothy (2 Timothy 6: 1-7)
The Solemnity of St Peter & St Paul, a Holy Day of Obligation, is on Wednesday. Plenty of Masses are available.
